Abstract

A specialty of silicon: A stable dimeric silaisonitrile (ArNSi:) ₂ (see picture; Ar=2,6-bis(2,4,6-triisopropylphenyl)phenyl) was prepared by the reduction of dichlorosilaimine IPrCl₂SiNAr with KC₈. The dimer is the first base-free disilylene with two-coordinate silicon atoms; reaction with trimethylsilyl azide affords the first bis(silaimine) (ArNSiNSiMe₃)₂ with three-coordinate silicon atoms.
