Abstract
AbstractIn this work, several alkenylated benzo[1,2‐b:4,5‐b′]dithiophene were synthesized by Pd‐catalyzed C−H functionalization of benzo[1,2‐b:4,5‐b′]dithiophene with various alkenes. This direct alkenylation took place regioselectively at the C‐2 position of the fused heterocycle. The obtained compounds were structurally characterized by NMR and MS spectroscopic methods. Moreover, DFT calculations have been employed to shed light on the regioselectivity of the reaction as well as on the geometry and electronic properties of the newly formed C=C double bonds.
