摘要：
A mild one-pot, three-component coupling reaction uniting a dialkyl phosphite, carbon disulfide (CS2) and an alkyl halide for the mild and efficient synthesis of phosphonodithioformates using cesium carbonate (Cs2CO3) and tetrabutylammonium iodide (TBAI) was developed. Various dialkyl phosphites were examined using a diverse array of alkyl halides, and these improved reaction conditions were found to be highly selective producing the title compounds exclusively in moderate to high yields.
