To get around the jargon, imagine a knife that would cut through an apple but not a peeled banana🔪🍎🍌

In @science.org this week the Leonori and Ruffoni groups show photoexcitation of nitroarene reagents selectively cleaves aryl C=C bonds over olefins

Excited-state configuration of nitroarenes enables oxidative cleavage of aromatics over alkenes
The ozonolytic deconstruction of aromatics remains a challenge in organic chemistry. Ozone preferentially reacts with alkenes over arenes, meaning that once the initial aromatic cleavage occurs, the d...

Turning nitroarenes into aromatic amines is a bread-and-butter organic chemistry reaction. But lots of these methods have drawbacks. A new reaction from P. Andrew Evans and Gregory Jerkiewicz sidesteps many of those. My latest in @cenmag.bsky.social.

Light-promoted aromatic denitrative chlorination - Nature Chemistry
Due to the inert CAr–NO2 bond, direct denitrative substitution reactions with unactivated nitroarenes are challenging. Now, using visible-light irradiation, a strategy has been developed to enable dir...

I think this is spot on. It was also one of the message @craigdcampbell.bsky.social and I were trying to make in our first bin the tin paper pubs.acs.org/doi/10.1021/...
Reflections on the Teaching Practices for the Reduction of Nitroarenes: Updating Methodologies and Considerations of the Mechanism
The reduction of nitroarenes to anilines is a key transformation with real-life context, central to the preparation of many important fine chemicals. The importance of this transformation has led to i...

Acetylene's not great; I guess I figured it was more predictable but maybe that's not true. I guess I see nitroarenes and go "ooh, problem?"
