WebSep 15, 2010 · The one-carbon extension of a carboxylic acid chain of an ester with methylene dibromide by means of strong base treatment at very low temperature and quenched by an alcohol is known as the Kowalski homologation. This reaction has obvious advantages over the Arndt–Eistert synthesis, and also bears some limitations. The two … In organic chemistry, a homologation reaction, also known as homologization, is any chemical reaction that converts the reactant into the next member of the homologous series. A homologous series is a group of compounds that differ by a constant unit, generally a methylene (−CH2−) group.
