Cp 2 TiMe 2 has been found to be a competent catalyst for the intramolecular hydroamination/cyclization of aminoalkynes. In the presence of 5.0 mol% Cp 2 TiMe 2 , the hydroamination reactions proceed smoothly at 100-110ยฐC to give five-and six-membered cyclic imines within 4-6 h. After subsequent red
