Cleavage of Tin-Carbon Bonds of Organosilylstannane and Organodistannane in Photo-Induced Electron Transfer Reaction and Mass Spectrometry

Article abstract of DOI:10.1246/cl.1995.29

Photoalkylation of tetracyanobenzene and benzil with (n-Bu)3SnSiMe3 or (n-Bu)3SnSn(n-Bu)3 proceeds via electron transfer.In these reactions, the Sn-C bond of (n-Bu)3SnSiMe3 and (n-Bu)3SnSn(n-Bu)3 is cleaved in preference to the Sn-Si and Sn-Sn bonds.Similar cleavage of the Sn-C bond is also observed in mass spectra of these group 14 organometallic compounds.
