Recent Progress in Decarboxylative Oxidative Cross Coupling

A short review article, also from the group of Igor Larrosa at Manchester, on the use of aromatic carboxylic acids as coupling partners in biaryl synthesis, appeared earlier in European Journal of Organic Chemistry (2017, 3517-3527). It is suggested in the micro-review that benzoic acid derivatives are atom-economic alternatives to traditional cross  coupling partners, and

Transition-Metal-Free Decarboxylative Bromination of Aromatic Carboxylic Acids

The brominative decarboxylation  reaction was demonstrated over a hundred and fifty years ago by Borodin (the famous composer, whose day job was as Professor of Organic Chemistry) and later developed by Hunsdiecker, whose name the reaction now bears. From an industrial viewpoint the transformation would be useful but the need to have a stoichiometric silver
