Co(ii), a catalyst for selective conversion of phenyl rings to carboxylic acid groups†
Abstract
An inexpensive protocol for the conversion of –C6H4R into –COOH groups using Co(II)–Oxone mixture as the catalytic system is described. A series of substrates containing substituted and non-substituted phenyl groups could be selectively converted into carboxylic acids. Initial mechanistic data have been provided.
