We report an expedient method for the heteroarylation of acetone tinder tin-free conditions. The coupling is performed using the commercially available enol silane of acetone (2-trimethylsilyloxypropene) and a corresponding ary, bromide, chloride or triflate under microwave-assisted conditions, with tris(dibenzylideneacetonc)dipalladium (Pd-2(dba)(3)) or palladium acetate (Pd(OAc)(2)) and 2-(2',6'-dimethoxybiphenyl)dicyclohexylphosphine (S-Phos) as the catalyst system.

Utilisation de 3 methodes electrochimiques pour determiner les reactivites d'une serie de 26 couples radical aryl-nucleophile
A novel method for transition-metal-free synthesis of 7-azaindoles is developed through a one-pot synthesis involving amination of pyridine N-oxides and intramolecular enamine formation. Remarkable features of the method include simple operation, mild reaction conditions, wide substrate scope, and easily accessible starting materials.
