A new method for selective C (5)–H alkylation of 2-substituted furans with tertiary and secondary alkyl bromides under photoinduced by visible light (∼ 460 nm) palladium catalysis has been developed. The method is relied on the use of available Pd (PPh 3) 4 catalyst under mild conditions (30±5° C, K 2 CO 3 as base), tolerates to various functional groups in furanic substrates and provides from good to excellent yields of alkylated products.
