Abstract

Abstract In contrast to tBu 2 SiN (Li) SiXtBu 2 (X= Cl, tBu), the silyl amide Me 2 SiClN (Li) SitBu 3 is unstable towards LiCl elimination, which means that the silanimine donor adduct Me 2 Si= NSitBu 3· NMe 2 Et can be synthesized in high yield from the reaction of Me 2 SiClN (H) SitBu 3 with nBuLi inthe presence of NMe 2 Et. The silanimine adduct tBu 2 Si= NSiCltBu 2· NMe 2 Et, with bulky tBu substituents at the unsaturated Si center, is ...
