Abstract
The organolanthanide complex (η5-Me5C5)2-SmCH(TMS) 2 serves as a precatalyst for the efficient and regiospecific hydroamination/cyclization of aliphatic and aromatic aminoalkynes RC≡C(CH2)nNH2 to yield the corresponding heterocycles RCH2C=N(CH2)n-1CH2. Kinetic and mechanistic evidence argues that the turnover-limiting step is intramolecular alkyne insertion into the Sm - N bond followed by rapid protonolysis of the resulting Sm - C bond.
