Have you ever stuffed up a reaction so badly that it was more interesting than the original experiment?

We report the development of a novel C-C decoupling reaction mediated by a palladium/bis(phosphine) catalyst system. This methodology is the first of its kind, and allows for the chemoselective scission of Ar-Ar bonds to give aryl halides and arylboronic esters. 

If you liked palladium-on-carbon, you’ll love the all-new palladium-on-lemon!
