center to the alkylhalide to form the corresponding alkyl radical, which has a finite lifetime before it undergoes C–C bond formation. Cobalt–N-heterocyclic carbene catalytic systems have been developed for chelation-assisted ortho-alkylation of aromatic compounds with alkylhalides. Aryl imines can be selectively monoalkylated at room temperature by various primary or secondary alkyl chlorides or

A process for forming a carbon-carbon bond to couple an aryl or heteroaryl group of a first compound with an alkyl or cycloalkyl moietyof a second compound, the process comprising reacting the first compound with the second compound in the presence of a catalytically effective amount of a neutral or cationic ruthenium(II) catalyst of formula (I).
