Abstract
A method for selective C(2)H alkylation of (benz)oxazoles with tertiary alkyl chlorides and alkyl bromides under photoinduced by visible light (460 nm) catalysis with Pd(PPh3)4/[Bu4N]I system in N,N-dimethylacetamide has been developed. Tetraalkylammonium salt has a significant promoting effect on the reaction which seems to be based on the stabilization of nanosized palladium species in the catalytic system.
