Acyl (phosphoryl) transfer by use of gem-dihalides
Abstract
gem-Dihalides are capable of promoting acyl transfer; for example, sym-diesters of pyrophosphoric acid are formed when 4-methoxybenzylidene dichloride is heated with a monoester of orthophosphoric acid. In the presence of an alcohol, ester formation occurs. Analogous acylations by use of carboxylic acids can be observed.
