Mixed reagents prepared in situ from the (aminosilyl)lithiums with i-PrMgBr undergo coupling reactions with chloro-oligosilanes without SiSi bond cleavage, which is a serious side reaction with the (aminosilyl)lithiums themselves. Based on the coupling reaction and the amino-to-chloro transformation, functionalized tetrasilanes and hexasilanes are synthesized. The analysis of the 1H- and 29Si-NMR

Two UV absorption maxima, around 220 and 280 nm, characteristic of a series of (amino)(phenyl)disilanes are interpreted in terms of the n-sigma conjugation between the nonbonding electrons on nitrogens and the Si-Si sigma-bonding electrons which are activated by the sigma-pi conjugation with the phenyl groups. The X-ray crystal structure of a 1,1,2,2-tetraamino-1,2,-diphenyldisilane has also been determined.
