An unexpected transformation of 1,6-diarylhexa-1,5-diene-3,4-diones (cinnamils) to 2,3,8-triaryl vinyl fulvenes via N-Heterocyclic Carbene (NHC) catalysis is reported. Mechanistic as well as synthetic novelty is the hallmark of this reaction.
据报道,通过N-杂环卡宾(NHC)催化,将1,6-二芳基六-1,5-二烯-3,4-二酮(肉桂)意外地转化为2,3,8-三芳基
乙烯基富烯。机械的以及合成的新颖性是该反应的标志。
