SOLID-PHASE CATALYSTS COMPRISING SUPPORTED FRUSTRATED LEWIS PAIRS

摘要

Solid-phase catalysts comprising a frustrated Lewis pair (FLP) immobilized on a support having a hydroxylated surface are disclosed. Also described are methods of making the solid-phase catalysts as well as their uses in hydrogenation reactions of olefins. The solid-supported FLPs present numerous catalytic advantages over FLPs known heretofore, including reduced reactor fouling, improved separation procedures and the ability to use the catalysts in continuous flow applications. Preferred FLPs comprise B(C6F5)3, B(C6CI5)(C6F5)2, P(tBu)3 and tetramethylpiperidine (TMP); preferred supports are silica and layered double hydroxides, in particular hydrotalcite.
