Novel Peralkylcyclotetrasilanes of the Type (R1R2Si)2(R3R4Si)2

Novel peralkylcyclotetrasilanes of the type (R1R2Si)2(R3R4Si)2 (R1 = R2 = t-BuCH2, R3 = R4 = i-Pr; R1 = R2 = t-BuCH2, R3 = t-Bu, R4 = Me) were obtained by co-condensation of two 1,2-dichlorotetra-alkyldisilanes with Li; the structure of the tetraisopropyltetraneopentylcyclotetrasilane (1), determined by X-ray crystallography, is folded with a large dihedral angle.
