Silver-catalyzed decarboxylative cross-coupling of α-keto acids with alkenes giving approach to chalcones
摘要:
A silver-catalyzed decarboxylative cross-coupling of alpha-keto acids with alkenes is reported. The method, with a wide range of substrate tolerance and mild operational conditions, can produce various chalcone derivatives in moderate to high yields from easily available starting materials.

An efficient and regioselective hydrodehalogenation of aromatic α‐ and β‐halo carbonylcompounds has been developed using CuI in isopropanol under basic condition. This reaction system effectively reduces chloride, bromide and iodide groups and affords high yield (up to 97 %) as carbonylcompounds. The method is environmentally friendly and demonstrates excellent tolerance to a broad range of electronically
