Palladium-catalyzed cross-coupling reaction of iodobenzene and its 4-substituted derivatives, except for 4-nitroiodobenzene, with (Z)-1-ethoxy-2-(tributylstannyl)ethene under a carbon monoxide atmosphere (5 atm) gave the corresponding (E)-3-ethoxy-1-arylprop-2-en-1-ones in considerable yields. Syntheses of chromone and 4(1H)-quinolinone were accomplished by application of this method to 2-(methoxymethoxy)iodobenzene and ethyl 2-iodophenylcarbanylate, respectively. The results obtained on the carbonylative coupling reaction of halopyridines are also described.

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
