Abstract

The reaction between the lithium 3-sila-beta-diketiminate (1) and the appropriate MOBut yielded the crystalline sodium (2) or potassium (3) 3-sila-beta-diketiminate in high yield; X-ray crystal data and NMR spectra show new coordination modes for the [N(R)C(Ar)Si(R)C(Ar)N(R)]- ligand (R = SiMe3, Ar = C6H3Me(2)-2,6).
