The thermolysis of 3, 4-benzo-1, 1, 2, 2-tetraethyl-1, 2-disilacyclobut-3-ene (2) at 250°C gave <I>o</I>-quinodisilane (1, 2-bis (diethylsilylene) cyclohexa-3, 5-diene) as a reactive species, while the photolysis produced a reactive silene, 1-ethyl-1- (2-diethylsilylphenyl) -1-silaprop-1-ene. The reaction of 2 with a catalytic amount of tetrakis (triethylphosphine) nickel (O) in benzene afforded a benzene adduct. 1-diethylphenylsilyl-2- (di-ethyl) silylbenzene in quantitative yield. Similar reaction of 2 with a catalytic amount of tetrakis (triphenylphosphine) palladium (O) in benzene yielded a dimerization product in high yield. With (η<SUP>2</SUP>-ethylene) bis (triphenylphosphine) platinum (O), 2 afforded an isomerization product of 2 as a major product. The nickel, palladium, and platinum-catalyzed reactions of 2 with various organic substrates have been described.
