When an allenic sulfone is treated under palladium catalysis in the presence of a weak acid, isomerization to a 1-arylsulfonyl 1,3-diene occurs. Investigations of the mechanistic aspects of this isomerization were performed, leading to the mechanism proposed herein. Some further studies of reaction parameters are reported.
当在弱酸存在下在
钯催化下处理烯丙砜时,发生异构化为1-芳基磺酰基1,3-二烯。对这种异构化的机理进行了研究,导致了本文提出的机理。报道了一些对反应参数的进一步研究。
