Abstract
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(PPh3)4 catalyst under mild conditions (30 ± 5 °C, K2CO3 as base), tolerates to various functional groups in furanic substrates and provides from good to excellent yields of alkylated products.
