Base free aryl coupling of diazonium compounds and boronic esters: self-activation allowing an overall highly practical process.
Boronic esters have long been considered as poor partners in cross-coupling reactions with arene diazoniums. Here is reported an unprecedented application of self-activated boronic esters in a base-free cross-coupling reaction with diazonium salts under mild and user friendly conditions.
