Abstract

Abstract: In methylene chloride-trifluoroacetic acid, cyclopropylcarbinols (la-e) underwent rapid ring-opening reactions leading to 4-substituted 3-butenyl-1-trifluoroacetate esters (2a- e). With 1, l-dicyclopropylbenzyl alcohol (lb) and tricyclopropylcarbinol (IC), multiple ring opening occurred leading to bis-and tristrifluoroacetates 4 and 5, respectively. With di-and triorganosilanes present in the reaction mixture, ring opening was suppressed and ...
