Computational studies on decarboxylative C?H alkenylations provided key insights into the solvent-robust nature of C?H activation/decarboxylation domino reactions. These properties were exploited for ruthenium(II)-catalyzed C?H alkylations by a decarboxylative process with ample scope under copper-free and silver-free reaction conditions.

Vinyl substituted heterocycles such as 2-vinylfuran (Ia) and 2-vinylpyridine (Ib) react with phenylisocyanate (II) in presence of (Lig)Ni0 (Lig = TCP) to form the tricyclohexylphosphane-5-azanickelacyclopentan-4-one derivatives (V).The structures and properties of these metallacycles are described.A catalytic 1/1 CC bond formation to give the α,β-unsaturated carboxylic acid amide X proceeds only with Ia (Lig = P(OiP)3) and not with Ib (Lig = PEt3, PPh3, P(OiP)3).Presumably, the different reactivities are not caused by electronic and/or steric factors of the 2-furyl- or 2-pyridyl-substituents, but by the donor properties of the N-atom in Ib.The N Ni interactions in the complex bis2-2-vinyl-μ-pyridine-nickel> (XIIb) can be detected by spectroscopic and crystal structure studies.
