Hydrocarbation chemistry proceeding from nickel carbenes.
Nickel carbene complex 2 [Ni(triphos)C(H)N(H)xylyl]2+(BF4-)2 reacts with alkenes quantitatively and regiospecifically to give the anti-Markovnikov hydrocarbation products. X-ray crystallography shows significant iminium alkyl character of the hydrocarbation products, similar to that observed in parent carbene 2. Mechanistic studies suggest the importance of a "hydride" pathway over "alkene" (metallocycle formation or carbocation) pathways.
