Reaction of tetramesityldisilene, 1, with cyclohexene oxide in benzene at 80 deg C gives silyl enol ether, 2, as the major product along with the products of epoxide deoxygenation, cyclohexene and the known tetramesityldisilaoxirane, 3; reaction of 1 with

The addition of a variety of sulfones and a sulfoxide to ditetrelenes (a disilene and a digermene) was examined. The reaction of benzenesulfonyl chloride with tetramesityldisilene or tetramesityldigermene results in the formation of the 1,2-addition products, 2-chlorotetramesityldisilyl- or digermylbenzenesulfinate. The addition of p-toluenesulfonyl chloride to the disilene gave the analogous product, 2-chlorotetramesityldisilyl p-toluenesulfinate. In contrast, benzenesulfonyl fluoride, diphenyl and dimethyl sulfone did not react with either the disilene or the digermene. The unprecedented formation of the sulfinates reveals a selective 2-electron reduction of the sulfur centres using ditetrelenes. The addition reactions of sulfonyl compounds illustrates the potential of ditetrelenes to serve as reducing agents which react rapidly, at room temperature under mild conditions. The reaction of tetramesityldisilene with diphenyl sulfoxide resulted in the formation of tetramesityloxadisilirane and with benzene sulfonic acid resulted in the formation of 1,1,2,2-tetramesityldisilyl benzenesulfonate.
The reactivity of tetramesityldisilene with epoxides: Dependence of product distributions on steric and structural characteristics of the epoxide

Mono- and 1,1-disubstituted epoxides react with tetramesityldisilene (1) to give disilyl enol ethers (5) five-membered rings (6) and the products of epoxide deoxygenation, alkenes and 1,1,2,2-tetramesityl-3-oxa-1,2-disilacyclopropane (4). Adducts 5 and 6 are formed with complete regioselectivity, suggesting involvement of an epoxide ring-opened intermediate. Product ratios vary systematically with a dependence on the steric properties of the epoxide. Single crystal X-ray diffraction results are given for 6a and 6g, the five-membered ring products derived from propylene and cyclohexene oxides.
