In protic media 1-acyl 2-cyclopropene derivatives undergo a highly selective ring expansion reaction leading to cyclobutenes. This homoallylic 1-(2-cyclopropenyl) 1-hydroxy- ethylium cation rearrangement is an excellent approach to difunctional cyclobutene derivatives.
在质子介质中,1-酰基2-环丙烯衍生物经历高度选择性的扩环反应,从而生成环丁烯。这种均烯丙基的1-(2-环丙烯基)1-羟基-乙基阳离子重排是制备双官能环丁烯衍生物的极好方法。
