Abstract
The phosphonodithioformates appeared versatile precursors to the (mercaptomethyl)phosphonates and derivatives, through sodium borohydride reduction in acetonitrile heated under reflux. By contrast, when the reduction was performed at room temperature with sodium borohydride, the (mercapto-alkylthio-methyl)phosphonates were exclusively obtained; reduction with BH3-Me2S (BMS) or with lithium diisopropylaminoborohydride also led to these hemidithioacetals. The aforementioned products of reduction were charaterized by the syntheses of various derivatives. In particular, S-phosphonyl trithiocarbonates, N-phenyl imidodithiocarbonate and dithiocarbamate were prepared.
