Rhodium(I) Complexes with Hemilabile N-Heterocyclic Carbenes: Efficient Alkyne Hydrosilylation Catalysts

A series of alkylammonium-imidazolium chloride salts [RImH(CH 2 ) n NMe 2 ]Cl·HCl (R = Me, t -Bu, Mes; n = 2, 3) have been prepared by alkylation of 1-substituted imidazole compounds with the corresponding chloro-alkyl-dimethylamine hydrochloride. These salts are precursors for the synthesis of a li... View More
