The structures and stability of silylenoids RBrSiLi2 (R=CH3, C(SiH3)3).

The structures and stabilities of RBrSiLi2 (R=CH3, C(SiH3)3) have been studied using ab initio and DFT methods. CH3BrSiLi2 and C(SiH3)3BrSiLi2 have three possible structures, the p-complex, the plain, and the folded structures. The plain and the folded structures are different from those of known structures of silylenoids. The energy of the plain structure… (More)
