The SO2 insertion into teraalkyltin compounds, R4Sn (R = CH3, C2H5, n-C3H7, i-C3H7, n-C4H9), was investigated depending on the presence of water, reaction temperature and reaction time. According to eqns. (1)–(5), the reaction products R3SnO2SR, R2Sn(O2SR)2, (R3Sn)2SO4, R2SnSO4 and R2SnSO3 were isolated. Especially; at low temperatures (<0°) the following order of decreasing reactivity of the teraorganostannanes
根据水的存在,反应温度和温度,研究了将SO 2插入四烷基锡化合物R 4 Sn(R = CH 3,C 2 H 5,nC 3 H 7,iC 3 H 7,nC 4 H 9)中的情况。反应时间。根据eqns。(1)–(5),反应产物R 3 SnO 2 SR,R 2 Sn(O 2 SR)2,(R 3 Sn)2 SO 4,R 2 SnSO 4和R 2分离出SnSO 3。尤其; 在低温(<0°)下,建立了teraorganostannanes对SO 2降低反应性的以下顺序:R = C 2 H 5 > CH 3 > nC 3 H 7 > nC 4 H 9 > iC 3 H 7
