Reactions of Monobutyltin Oxide with Dialkyl and Alkylene Dithiophosphoric Acids: Synthesis and Spectral Studies.

Abstract Monobutyltin(IV) dialkyl and alkylene dithiophosphates, [OSnBuS2P(OR)2]2, HOSnBu[S2P(OR)2]2, (R = Prn, Pri, Bui and Ph), [OSnBuS2POCH2CMe2CH2O]n HOSnBu[S2POCH2CMe2CH2O]2, BuSn[S2P(OR)2]3 (R = Ph and Bui) and BuSn[S2POCH2CH2CH(Me)O]3 have been synthesized by the reactions of monobutyltin oxide with dialkyl and alkylene dithiophosphoric acids, in 1:1, 1:2 and 1:3 molar ratios in refluxing benzene. These products have been characterized by molecular weight determinations, NMR (1H, 13C, 31P and 119Sn), IR and elemental analyses. Plausible structures have been suggested.
