The ability of heteroallenes to undergo metathesis reactions could be demonstrated using the carbodiimides 2 . The stoichiometric reaction 1 + 2 → 3 + 4 is the first example of a metathesis of heteroallenes with carbene complexes such as 1 . The isocyanidetungsten complexes 3 thus obtained function as catalysts for the (equally novel) metathesis of symmetrical to “mixed” carbodiimides RNCNR′.
