Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>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(Im^DippN){N(SiMe₃)₂}₃] (<bold>1</bold>) was applied as a precatalyst for the addition of EH (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 <bold>1</bold> displaying high tolerance toward functional groups and heteroatoms.</p> </abstract>
