摘要：

Photo-induced electron transfer oxygenation of 3-phenyl-1,1,2,2-tetramesityl-1,2-disiletene(1) in acetonitrile-methylene chloride afforded the corresponding 1,2,3,6-dioxadisilin (2) in moderate yield as a dioxygen insertion product into a silicon-silicon sigma-bond together with 1,2,5-oxadisilolene (3). The results are reasonably accounted for by an electron transfer from disiletene 1 to the excited singlet state of the sensitizer to form a radical ion pair followed by addition of oxygen.
