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.
