Synthesis of Symmetrical and Unsymmetrical 1,2-Diketones through Cathodic Intramolecular Coupling of Diesters.
摘要:
Electroreduction of diesters [(RCOO)-C-1(CH2)(2)OCOR2] with Mg electrode has been found to give the corresponding unsymmetrical 1,2-diketones ((RCOCOR2)-C-1) with excellent yields. (C) 1997 Elsevier Science Ltd.
