✦ Synopsis

The reactions of homologues of Davy's reagent 1 and Lawesson's reagent 9 with trimethylalkylthiosilanes 2, trimethylsilyl enol ether 4, trimethyl(di-ethy1amino)silane 7, trialkylalkoxystannanes 14, and trialkyhlkylthiostannane 15 were studied. On the basis of these studies, novel advantageous methods of synthesizing S-trialkylsilyl and stannyl esters of tetrathio-, trithio-, and amidotrithiophosphoric acids 3, 5, 6, and 4-methoxyphenyldithio-and trithiophosphonic acids 10-113 were developed INTROD UCTIOAY Organophosphorus compounds of silicon and tin possess properties of practical use [ 1-31. S-Trimethylsilyl dithiophosphates are important intermediates for synthesizing useful organothiophosphorus compounds [ 11. S-Triorganotin dithio-and tetrathiophosphates are used as pesticides and as additives for lubricants [2,3]. Organosilyl and stannylthiophosphorus compounds were obtained by the reactions of 2,4-bis substituted 2,4-dithioxo-1 ,3,2A5,4h5-dithiadiphosphetanes with heptamethyldisilazane [4], trimethylsilylazide 151, trimethylchlorosilaiie [ 6 ] , trimethyl(dimethylamin0) "To whom correspondence should be addressed.
