Abstract

Evidence for disilene dimerization was obtained by generating tetraisopropyldisilene from the title compound the photochemical retrodiene process which produced the expected dimerization product, octaisopropylcyclotetrasilane (30%), in addition to the H-abstraction product, 1, 1, 2, 2-tetraisopropyldisilane (5%).
