标题:Electrochemical synthesis of niacin and other N-heterocyclic compounds
发明人：TOOMEY JR JOSEPH E
权利人:REILLY IND INC
摘要:An electrochemical oxidation of a pi-deficient N-heterocyclic precursor compound having an oxidizable organic group attached by a carbon-to-carbon linkage. This precursor compound is at least sparingly water soluble. The preferred electro-oxidation is conducted at an effective anode and in a medium which consists essentially of water, carboxylic acid, and the precursor compound. Preferred are electro-oxidations of substituted pyridine and quinoline bases and a particularly preferred aspect provides a convenient electrochemical synthesis of niacin from 3-methylpyridine.
