Reactivity of metal–metal bonds. IV. The reaction of sulfur dioxide with compounds containing Sn—Sn and Sn—Mn bonds

Abstract

The reactions of sulfur dioxide with the compounds R₆Sn₂ and R₃SnMn(CO)₅ (R = CH₃ or C₆H₅) have been studied. In all cases the evidence indicates that the metal–metal bond has been cleaved. With the ditins the new compounds R₃Sn_•SO₂ (R = CH₃ or C₆H₅) and R₃Sn_•2SO₂ (R = C₆H₅) were obtained, while the mixed bimetallic compounds gave R₃SnMn(CO)_5•2.5SO₂ (R = CH₃ or C₆H₅) and R₃SnMn(CO)_5•1.5SO₂ (R = CH₃). The possible structures of these derivatives are discussed.
