Palladium-Catalyzed Formylation of Arylzinc Reagents with S-Phenyl Thioformate

The first example of palladium-catalyzed direct fotmylation,a arylzinc reagents using S-phenyl thioformate is reported. The reaction proceeded: under mild conditions, allowing high functional group tolerance. In: addition, the developed fotmylation method was used to prepare deuterated and C-13-labeled aryl aldehydes from isotope-labeled S-phenyl;., thioformates. Moreover, this procedure was applied to an alkenylzinc halide, affording the corresponding end.
