Triphenylphosphine‐2,4,4,6‐tetrabromo‐2,5‐cyclohexadienone Complex as a Reagent for Preparation of Carboxylic Acid Bromides.

Abstract

2005Carboxylic amides Q 0490Triphenylphosphine-2,4,4,6-tetrabromo-2,5-cyclohexadienone Complex as a Reagent for Preparation of Carboxylic Acid Bromides. -It is noteworthy that this methodology for the preparation of acid bromides is chemoselective, and it can be applied to polyfunctional compounds such as hydroxy acids. The bromides are identified by conversion to the corresponding anilides (III). -(MATVEEVA, E. D.; PODRUGINA, T. A.; SANDAKOVA, N. G.; ZEFIROV, N. S.; Russ.
