Abstract
The use of phase transfer catalysis, PTC, for nucleophillic substitution reactions is well documented.1,2 Included among these reactions is the preparation of both alkyl3 and aryl4 thiocyanates. However, PTC reactions at an acyl carbon are much less common. Brándstróm5 has reported the preparation of acyl azides and Weber6 has used PTC to prepare benzoyl cyanide. Recently Illi7 has used PTC to acylate sterically crowded phenols.
