One-Pot Pd-Catalyzed Hydrostannation/Stille Reaction with Acid Chlorides as the Electrophiles. -The performance of the hydrostannation/Stille coupling of alkynes with acid chlorides in two steps with addition of the acid chloride after vinylstannane formation avoids the problems occurring by the presence of these reactive partners during the hydrostannation. The combination of Me3SnF/PMHS is successfully employed as an in situ trimethyltin hydride source to generate vinylstannanes by reaction with alkynes. Both aromatic and aliphatic acid chlorides give good yields of α,β-unsaturated ketones. An exception is the coupling of 2-nitrobenzoyl chloride which affords the decarbonylated product. -(LEE, K.; GALLAGHER, W. P.; TOSKEY, E. A.; CHONG, W.; MALECZKA*, R. E. J.; J.
