摘要
Excellent Z or E selectivity is observed in the Horner-Wadsworth-Emmons reactions of methyl bis(trifluoroethyl)phosphonoacetate 2 with aryl alkyl ketones 3a-d or aldehydes 3f,g using Sn(OSO2CF3)(2) in the presence of N-ethylpiperidine, which should have a different reaction mode to those using sodium hydride.
