Cellosolve benzoate

Orthoesters. As model experiments (1) phenyl Cellosolve and tetraphenyl orthocarbonate, and (2) hydroxyethyl benzoate and tetra-phenyl orthocarbonate reacted at 275°C. Diphenyl carbonate was obtained from the latter reaction but not from the former. The facts that the distillate from the latter reaction contained ethylene oxide and that diphenyl carbonate was formed quantitatively from the reaction of carboxylic acid and tetraphenyl orthocarbonate suggest the following reaction mechanism ...
