Transition metal imide organic imine metathesis reactions: unexpected observations
Mixtures of [Ti(NBut)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(NBut)H, the products of Ti=N-But/C=NAr transition metal imide/organic imine metathesis; examination of the kinetics for Ar = C6H4Me-4 showed that the rate limiting...

| Summary: | Mixtures of [Ti(NBut)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(NBut)H, the products of Ti=N-But/C=NAr transition metal imide/organic imine metathesis; 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. |
