Abstract

Organolanthanide complexes of the general type Cp'2LnCH (TMS) 2 (Cp'= η5-Me5C5; Ln= La, Sm, Y; TMS= SiMe3) and CGCSmN (TMS) 2 (CGC= Me2Si (η5-Me4C5)(t BuN)) serve as effective precatalysts for the rapid, regioselective, and highly diastereoselective intramolecular hydroamination/cyclization of primary and secondary amines tethered to conjugated dienes. The rates of aminodiene cyclizations are significantly more rapid than ...
