Reactions of tert-Butylperoxy Esters. XV. Decomposition of Dialkyl tert-Butylperoxy Phosphates

Abstract

The thermal decomposition of dialkyl tert-butylperoxy phosphates, in the presence and absence of solvents, yields the corresponding dialkyl phosphate, acetone, methanol, 2,2-dimethoxypropane, and methyl isopropenyl ether as the primary products. Prolonged heating of the product mixture produces trialkyl phosphates, (RO)3P(O), which arise from the thermal decomposition of dialkyl phosphates. Data are presented to support a mechanism involving the heterolytic cleavage of the peroxide linkage.
