A decarbonylative cyanation of aromaticesters with aminoacetonitriles in the presence of a nickel catalyst was developed. The key to this reaction was the use of a thiophene-based diphosphine ligand, dcypt, permitting the synthesis of aryl nitrile without the generation of stoichiometric metal- or halogen-containing chemical wastes. A wide range of aromaticesters, including hetarenes and pharmaceutical

acyl C–O bond borylative and silylative cleavage depends on the appropriate choice of different ligands and additives in the presence of nickel catalyst. Both transformations exhibit good functional group compatibility and can serve as powerful synthetic tools for late-stage functionalization of complex compounds. The elucidation of key mechanistic features of this newly developed acyl C–O bond activation
