Abstract

Unprecedented catalytic reactivity of actinide coordination complexes toward heterocumulenes, such as carbodiimides, isocyanates, and isothiocyanates is reported. The mono(imidazolin-2-iminato) thorium(IV) complex [Th(ImDippN){N(SiMe3)2}3] (1) was applied as a precatalyst for the addition of EH (E=N, P, S) bonds to the YCX core (Y=R2N; X=NR2, O, S) of carbodiimides, isocyanates, and isothiocyanates. The respective insertion products were obtained in high yields under mild reaction conditions, with complex 1 displaying high tolerance toward functional groups and heteroatoms.
