Catalysed decomposition of bis(ethoxythiocarbonyl) sulphide with tributylphosphine. A kinetic study in dimethyl sulphoxide, acetonitrile, and their mixtures with toluene

Abstract

The reaction of bis(ethoxythiocarbonyl) sulphide (1) with tributylphosphine in acetonitrile, dimethyl sulphoxide, and in their mixtures with toluene was subjected to kinetic study. The effect of water content in acetonitrile was also investigated. Activation parameters were measured and related to charge development in the formation of the first transition state, in accord with the proposed mechanism.
