Process for the preparation of 2-dialkoxy phosphinylimino-1,3-dithietane

摘要

There is provided a process for preparing 2-diethoxyphosphinylimino-1,3-dithietane by reacting diethoxyphosphinyldithiocarbamate with a methylene halide in an aqueous medium and in the presence of phase transfer catalyst whereby said dithietane is recovered in good yields.
