WebKochi reaction. The Kochi reaction is an organic reaction for the decarboxylation of carboxylic acids to alkyl halides with lead tetraacetate and a lithium chloride or other lithium salts [1] . WebSep 15, 2010 · Abstract. The carboxylic acids conversion into corresponding halides via the oxidative degradation of carboxylic acid by lead tetraacetate (LTA) accompanied by a simultaneous replacement with a halogen under free-radical conditions in the presence of a stoichiometric amount of metal halide is referred to as the Kochi reaction.
