The effect of added molecular sieves on alkene epoxidation reactions catalysed by [MoO2Cl2L], where L is a 3-(diethoxyphosphoryl) derivative of camphor

Abstract

Addition of molecular sieves to the alkene epoxidation system consisting of Bu^tOOH and [MoO₂Cl₂L], where L is a 3-(diethoxyphosphoryl) derivative of camphor increases both the rate and yield of the epoxidation reactions; for styrene maximum conversions of 25% which are subsequently degraded are converted to stable conversions of 96% with 94% selectivity to styrene oxide by adding 4A molecular sieves.
