A heterogeneous palladium catalyst hybridised with a titanium dioxide photocatalyst for direct C–C bond formation between an aromatic ring and acetonitrile

A palladium catalyst hybridised with a titanium dioxide photocatalyst can promote cyanomethylation of an aromatic ring by using acetonitrile, where the photocatalyst activates acetonitrile to form a cyanomethyl radical before the C-C bond formation using the palladium catalyst.
