The palladium-catalyzed cross-coupling reaction of bromobenzenes or bromoheteroarenes such as pyridine, thiophene, indole with (Z)-1-ethoxy-2-tributylstannylethene gives good yields of the corresponding (Z)-1-ethoxy-2-(aryl and heteroaryl)ethenes. This method is effective for introducing an ethoxyethenyl group into an aromatic and heteroaromatic ring and is proved to have versatile utility for the construction of benzo[b]furan, indole, isocoumarin rings 2-bromophenol, 2-bromoaniline, and 2-bromobenzoate derivatives.

The reaction of 4-substituted bromobenzenes, except for 4-bromophenol and 4-bromoaniline, with (Z)-1-ethoxy-2-tributylstannylethene is well prompted by the catalytic action of dichlorobis(triphenylphosphine)palladium in dimethylformamide in the presence o
