Abstract

Abstract The boron trifluoride catalysed rearrangement of 1,2-epoxyoctane to give octanal proceeds by selective (c. 1.4 : 1) migration of the prochiral hydrogen trans to the alkyl group. ... Introduction The intermediacy of carbonium ions is now well established1-4 for acid-catalysed rearrangements where the epoxide contains a tertiary carbon. The mechanism of intramolecular acid-catalysed reactions of epoxides which do not contain tertiary epoxide carbons is however less well ...
