Highly selective trimerisation of MeNC by a novel titanium imido complex containing a tridentate dianionic ligand

Abstract

A new type of imido compound [Ti(NBu ^t )L(py)] 1 containing a tripodal dianionic ligand is reported which effects the remarkably selective trimerisation of MeNC; the crystal structures of 1 and [TiL{N(Me)N(Bu ^t )(C ₄ H ₃ N ₂ M e)}] 2 are described [L = MeC(2-C ₅ H ₄ N)(CH ₂ NSiMe ₃ ) ₂ ].
