Synthesis and Vibrational and Mass Spectra of (n-Bu)2Sn(O2PMe2)2, (n-Bu)2Sn(O2PMePh)2 and (n-Bu)2Sn(O2PPh2)2

Di-n-butyltin dimethylphosphospinate has been synthesized by the reaction of (n-Bu)2Sn(OCOCH3)2 with HO2PMe2 in benzene.The reactions of (n-Bu)2Sn(OCOCH3)2 with MePhPOCl and Ph2POCl in toluene have been used to prepare (n-Bu)2Sn(O2PMePh)2 and (n-Bu)2Sn(O2PPh2)2 respectively.On the basis of vibrational spectra and physical properties it is concluded that the title compounds are polymerized and the ligands function as O-P-O bridges between the tin atoms.The n-butyl groups are in trans position in the resulting octahedral environment around tin.Loss of n-butyl radicals and of the diorganophosphinate group from tin represent the main fragmentation processes in the EI mass spectra of (n-Bu)2Sn(O2PRR')2 (RR' = Me2, MePh, Ph2).The mass spectra show Sn(O2PRR') as the base peak. - Keywords: IR Spectra, Raman Spectra, Mass Spectra, Di-n-butyltin Dimethylphosphinate
