The reaction of dilithiosilane, ((Bu2MeSi)-Bu-t)(2)SiLi2 (2), with 1,1,2,2-tetrachloro-1,2-dimesityldisilane produced the tetrasila-1,3-butadiene derivative ((Bu2MeSi)-Bu-t)(2)-Si=Si(Mes)(Mes)Si=Si((SiMeBu2)-Bu-t)(2) (3; Mes = 2,4,6-trimethylphenyl) as reddish purple crystals. The reaction of 3 with (BuLi)-Bu-t in THF produced 1, 1-bis(di-tert-butylmethylsilyl)-2-lithio-2-mesityldisilene (4) as red crystals, which is an sp(2)-type silyllithium species, by the reductive cleavage of the central Si-Si bond in 3.
