Methyl- and ethyl-vinylketene were added to several simple olefins to afford alkylated 2-vinylcyclobutanones , which in turn rearranged to cyclopentenones (via dienones ,) or (via 1,2-acyl migration) under acid catalysis. Evidence is presented for a cyclopropyl-carbinyl intermediate .
将甲基和乙基乙烯基乙烯酮添加到几种简单的烯烃中,以提供烷基化的2-乙烯基环丁酮,然后在酸催化下将其重排为环戊烯酮(通过二烯酮)或(通过1,2-酰基迁移)。提供了环丙基-羰基中间体的证据。
