The α-amination reaction of ketones was studied and the reaction conditions were analysed by green metrics. Propiophenone and two aliphatic ketones, saturated cyclic and acyclic secondary amines were used, carbohydrate Cu2+ complexes were the catalysts to obtain the brominate intermediates. Traditional stirring and ultrasound methods were compared. The use of α-CDCuBr2 complex in the presence of propiophenone, morpholine and O2 was the best condition to carry out the α-amination reaction using a One Pot synthesis, with an 80 % yield of product isolated and no by-product was detected.
