Novel zwitterionic complexes of Ti(IV) via reaction of Lewis acids M(C6F5)3 (M = B, Al) with a titanium diene complex (η5-C5Me4SiMe2NtBu)Ti(1,3-pentadiene)
Abstract
The reaction of (η5-C5Me4SiMe2NtBu)Ti(1,3-pentadiene) with B(C6F5)3 or Al(C6F5)3 in 1:1 mole ratio in hexane solution at room temperature results in the formation of titanium borate or aluminate zwitterions which both feature stabilisation of the Ti(IV) centre by two agostic Ti⋯H–C interactions.
