N-heterocyclic carbenes as highly efficient catalysts for the cyclotrimerization of isocyanates.

Hung A Duong1, Michael J Cross, Janis Louie.   

Abstract

[reaction: see text] A series of N-heterocyclic carbenes (NHCs) were evaluated as potential catalysts for the cyclotrimerization of isocyanates to afford isocyanurates. 1,3-Bis-(2,6-diisopropylphenyl)-4,5-dihydroimidazol-2-ylidene (SIPr) was found to be a highly efficient catalyst for the cyclotrimerization of a variety of isocyanates.
