The cyclotetrasilane [(i-Pr)2Si]4 reacts with K in benzene in the presence of 18-crown-6 to give the 1,4-dipotassio compound K[(i-Pr)2Si]4K (1). The reaction of 1 with (i-Pr)2SiCl2 and Me3SiCl leads to the formation of the sterically crowded oligosilanes, [(i-Pr)2Si]5 (2) and Me3Si[(i-Pr)2Si]4SiMe3 (3), respectively. The molecular structures of the resulting oligosilanes, 2 and 3, display some unusual features.

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