摘要

This contribution reports the efficient and regiospecific Cp'2LnCH (SiMe3) 2 (Ln= La, Nd, Sm, Lu; Cp'= η5-Me5C5)-and Me2SiCp''2LnCH (SiMe3) 2 (Ln= Nd, Sm; Cp''= η5-Me4C5)- catalyzed hydroamination/cyclization of aliphatic and aromatic aminoalkynes of the formula RC⋮ C (CH2) nNH2 to yield the corresponding cyclic imines RCH2C N (CH2) n-1CH2, where R, n, N t h-1 (° C)= Ph, 3, 77 (21° C); Ph, 3, 2830 (60° C); Me, 3, 96 (21° C); CH2 ...
