Allylic alcohols, 1-buten-3-ol, 1-penten-3-ol and 1-octen-3-ol, reacted with aryl iodides (iodotoluene, 4-iodotoluene, 4-iodophenol and 4-iodanisole) under Heck reaction conditions to form corresponding saturated aryl ketones in one step. The same products were obtained in a two-step tandem reaction consisted of the Heck coupling of allylic alcohols with aryl iodides, followed by hydrogenation. Reactions were catalyzed by phosphorus-free palladium precursors modified with the menthol-substituted imidazolium chlorides. Formation of crystalline palladium nanoparticles, of the diameter up to 65 nm, in the reaction mixture was evidenced by TEM.

N-Heterocyclic carbene-palladium(II)-1-methylimidazole [NHC-Pd(II)-Im] complex 1 showed efficient catalytic activity toward α-arylation of symmetric dialkyl ketones under mild conditions. It was found that the ratio of aryl chlorides and ketones drastical

An easily available NHC-Pd(II)-Im (NHC=N-heterocyclic carbene, Im=1-methylimidazole) complex was found to be an efficient catalyst for the α-arylation reaction between ketones and aryl chlorides. Under the optimal conditions, all reactions proceeded smoot
