title: N-heterocyclic carbenes--catalysts for the preparation of polyhedral silsesquioxanes.
abstract: N-Heterocyclic carbenes could be used as powerful catalysts for the preparation of various polyhedral silsesquioxanes. NHCs also catalyze a rearrangement of existing cages and a scrambling between two different cages at a concentration as low as 1 mol%.
