Abstract

Abstract Mono-and di-substituted alkynes react with CO and secondary amines such as Et 2 NH in the presence of Ni II salts to form carbamoyl products of the types Et 2 NCOC (R) C (R′) CONEt 2 and RC CCONEt 2. Depending on the NiX 2 salt (X= Cl, Br, I) employed and the temperature (20–100 C), a product selectivity is observed. The mechanism of the reaction is discussed.
