Abstract
In this study, we report a novel and efficient one-pot synthesis of mixed phosphorotrithioates under mild conditions at ambient temperature, obviating the requirement for supplementary additives. The method's versatility stems from its utilization of diverse thiols as nucleophilic reactants, 1-chloro-N,N,N′,N′-tetraisopropylphosphanediamine [bis(diisopropylamino)chlorophosphine] as the phosphorus precursor, and various sulphenyl chlorides as sources of electrophilic sulfur. Notably, our investigation extends beyond mixed phosphorotrithioates to encompass the synthesis of phosphoroselenodithioates, underscoring the broad applicability of this synthetic protocol.
