摘要：

Treatment of ethyl alpha-per(poly)fluoroalkyl acetates 1 or ethyl alpha-iodo-beta-per(poly) fluoroalkyl acrylates 2 with hydrazine gives 3-hydroxy-5-per(poly)fluoroalkyl pyrazoles 3 in excellent yield. The effect of halogens on the pert polyfluoroalkyl chain and the reaction conditions were studied.
