Thermal rearrangement of diphenyl carbonate

Abstract

The thermal degradation of diphenyl carbonate has been examined in the gas and condensed phases. From a detailed analysis of the products it is suggested that the mechanism involves an initial rearrangement to 2-phenoxy benzoic acid followed by several competing reactions of the acid. The effect of phase is discussed. The thermal behaviour of several compounds involved in the degradation scheme has also been investigated.
