The Dual Role of Benzophenone in Visible‐Light/Nickel Photoredox‐Catalyzed C−H Arylations: Hydrogen‐Atom Transfer and Energy Transfer

by Abhishek Dewanji, Patricia E. Krach, Magnus Rueping
Angewandte Chemie International Edition The Dual Role of Benzophenone in Visible‐Light/Nickel Photoredox‐Catalyzed C−H Arylations: Hydrogen‐Atom Transfer and Energy Transfer

Benzophenone resurrected: The inherent reactivity of benzophenone upon photochemical excitation is used for the aliphatic C−H arylation reaction. The conditions are tolerant to a broad range of functional groups. Mechanistic experiments shed light on the dual role of the new photocatalyst of the metallaphotoredox family.


Abstract

A dual catalytic protocol for the direct arylation of non‐activated C(sp3)−H bonds has been developed. Upon photochemical excitation, the excited triplet state of a diaryl ketone photosensitizer abstracts a hydrogen atom from an aliphatic C−H bond. This inherent reactivity was exploited for the generation of benzylic radicals which subsequently enter a nickel catalytic cycle, accomplishing the benzylic arylation.

The Official Fast Food French Fry Power Rankings

by John Gruber

It is astounding how strongly I agree with these rankings from Lucas Kwan Peterson at the LA Times. I know it’s fighting words to slag on In-N-Out, but their fries really are dreadful:

And bringing up the rear is In-N-Out. Before you tell me there’s a way to “hack” these fries, or somehow make them better, either by loading them with American cheese and secret sauce, or by ordering them well-done, I will grant this: It certainly doesn’t make the fries any worse. Just as dumping the fries into a dirt pile on the shoulder of a highway access road and running over that pile with my car would also probably not make the fries any worse.

Link round-up for 17 February 2019 (delayed)

by Infidel753
Various interesting stuff I ran across on the net over the last week.

o o o o o

The first trailer for Frozen 2 has come out!

You can't tell me this wasn't intentional.

Plormp!

He hides in plain sight.

Visit Canada's bird, avoid stress Satanically, and more.

When designing a machine, think ahead.

Here's how to determine the date of a world map.

And he can only move diagonally.

I guess the altar boy is giving the sermon.

A young musician draws an appreciative audience.

Debra She Who Seeks has dancing goddesses (slightly NSFW).  Calvin has some creepy critters.

Oh, the things religious nuts have to worry about.

Is she a witch?

OK, this is the kind of news item you don't see every day.

Trees, trees, trees!

He's hot as Hell.

Most clueless management ever.

This is Johannesburg.

Such self-righteous scum really exist.

Crazy Eddie and friends compare Trump to various kinds of extinct mammals.

Mark Alpert has written a novel about a curiously-familiar fictional President.

Not good news for my own job-hunting.

Gosh, what precaution could she possibly take?

This is an obvious scam and wouldn't even make a good cartoon.

The witch game teaches kids a valuable lesson.

This outcome was predictable, inevitable, and unforgivable.

Catholics who support the Christian Right had better hope it never actually wins.

Mass paranoia leads to harassment and worse.

Here's how Americans debate health-care reform.  Most Americans have no clue about realistic health costs.

Look for answers, don't just make them up.

The "woke" bullcrap will reduce fanfic to the level of those godawful Christian novels.

Republicans are afraid of everything, even Trump.

Can humans change God's mind?

This looks like good advice for anyone, not just writers.

Discrimination thrives in Pence's former state.

Other people's taste in sexual fantasy is just as valid as yours.

Petty, slimy, hateful language meant only to wound and insult -- nice going, Christians.

Google's "do not track" setting is basically fake.  They're going to try to sabotage your ad-blocker too.

Apparently the next big thing in consumer gadgetry will be this "mirrorworld" concept.  At first reading, it sounds to me like a horribly intrusive and commercialized nightmare.

Professor Chaos looks at idiots in the news.

This book is evil.

There's now a video game for conservatives.

A sports-store owner boycotted Nike to protest its Colin Kaepernick ad, with predictable results.

Republicans have weaponized the most gullible segment of the US population.  They're basically working toward this (found via Calvin).

What seems like evil is often just indoctrination.

Legalization of teh shrooms gets some surprising support.

The White House communications chief is married to a lunatic.

See if you can guess why Fox News rejected this ad.

Disaster is good for business.

A massive sexual-abuse scandal has erupted within the hypocritical Southern Baptist Convention.

Michigan is about to tell the cops to stop stealing stuff.

Let the Trumpanzees suffer the consequences of their stupidity.

The Christian God is as far from "love" as it's possible to get.

Pompeii is still being excavated, giving us new glimpses into ancient Roman life.

Oh, great, a flying lizard the size of a giraffe (don't worry, they're all long dead).

Hackwhackers remembers Opportunity.

The US and Europe team up to test a defense against asteroid impacts.

How much water an Earth-like planet has may depend on whether a supernova happens nearby at a certain stage of solar-system formation.

Here's why the British tend to dislike Trump.

British students take a stand against the barbarity of halal and kosher meat (though administration lags behind).

With the US an unreliable ally under Trump, another powerful nation must take a larger role in European security.

This seems like a useful form of "cultural appropriation", if true.

A vibrant Asian democracy is standing up to the world's biggest gangster state.

The rule of a religio-nationalist party is eroding science in India (sounds familiar).

The Ebola outbreak in the war-torn eastern Congo is getting worse.

Half of Republicans believe Trump was chosen by God.

Start preparing now for the next election.

Shower Cap wonders why Trump prefers "his face looking like rhino's butthole after it sat on a crate of apricot jelly beans", and contemplates the "national emergency" and its aftermath.

Achieving Over 15% Efficiency in Organic Photovoltaic Cells via Copolymer Design

Advanced Materials Achieving Over 15% Efficiency in Organic Photovoltaic Cells via Copolymer Design

Organic solar cells achieve over 15% efficiency through the use of a copolymer donor, and simultaneously enhanced open‐circuit voltage and short‐circuit current density are obtained. High‐performance solar cells are adaptable for environment‐friendly solvents using a blade‐coating method, while showing better photostability than the corresponding ternary solar cells.


Abstract

Ternary blending and copolymerization strategies have proven advantageous in boosting the photovoltaic performance of organic solar cells. Here, 15% efficiency solar cells using copolymerization donors are demonstrated, where the electron‐withdrawing unit, ester‐substituted thiophene, is incorporated into a PBDB‐TF polymer to downshift the molecular energy and broaden the absorption. Copolymer‐based solar cells suitable for large‐area devices can be fabricated by a blade‐coating method from a nonhalogen and nonaromatic solvent mixture. Although ternary solar cells can achieve comparable efficiencies, they are not suitable for environment‐friendly processing conditions and show relatively low photostability compared to copolymer‐based devices. These results not only demonstrate high‐efficiency organic photovoltaic cells via copolymerization strategies but also provide important insights into their applications in practical production.
