A NEW METHOD FOR SYNTHESIZING DIALKOXYTIN(II) AND MONO AND DIARYLOXYTIN(II) COMPOUNDS

摘要

The reactions of bis(beta-diketonato)tin(II), such as bis(2,4-pentanedionato)tin(II), Sn(acac)(2), bis(1-ethoxy-1,3-butanedionato)tin(II), Sn(etac)2, and bis(1-methoxy-1,3-butanedionato)tin(II), Sn(mtac)(2), with sodium alkoxide (NaOR, R = CH3, C2H5) in alcohol/benzene at room temperature have been found to give the corresponding dialkoxytin(II) compounds. Sn(acac)(2) reacted also with o-substituted phenols [o-X-C6H4OH; X = CH3CO, CH3OC(O), CH3O, Cl, (CH3)(3)C] in a molar ratio of 1:2 at 90 degrees C to afford the corresponding monosubstituted tin(II) compound, [Sn(OC6H4-X)(acac)], but the reaction with C6H5OH produced only the diphenoxide, Sn(OC6H5)(2).
