Abstract
A process for the preparation of a Group 4 metal amide complex comprising a monovalent or divalent Lewis base ligand the steps of the process comprising contacting a Group 4 metal amide with a neutral source of a monovalent or divalent, Lewis base ligand group and a solid Lewis acid scavenging agent under amine elimination conditions to form a Group 4 metal amide complex containing at least one less amide group per metal moiety than the initial Group 4 metal amide.
