Transition metal imide/organic imine metathesis reactions: unexpected observations

Abstract

Mixtures of [Ti(NBu^t)Cl₂(py)₃] 1 and PhC(NAr)H (Ar = C₆H₃Me₂-2,6 or C₆H₄Me-4) gave quantitative conversion to [Ti(NAr)Cl₂(py)₃] and PhC(NBu^t)H, the products of TiNBu^t/CNAr transition metal imide/organic imine meta-thesis; examination of the kinetics for Ar = C₆H₄Me-4 showed that the rate limiting step for this process is zero order in [1], demonstrating that these reactions do not involve metal imide particiption in the rate limiting step.
