Two- and four-carbon homologation of aldehyde by AgClO4-catalyzed addition of alkoxyalkenylzirconocene chloride
摘要:
Two- and four-carbon homologation of aldehyde is described, which is based on the AgClO4-catalyzed addition of zirconocene complexes, derived from hydrozirconation of 1-ethoxyethyne (1) and (Z)-1-methoxy-1-buten-3-yne (2) with Cp2Zr(H)Cl, followed by acidic hydrolysis.
