Abstract: A new method for the preparation of active catalysts for the alkylation and transalkylation of aromatic compounds (benzene and toluene) based on aluminum chloride immobilized on the surface of silica gel was developed. The alkylation occurred wi
New Heterogeneous Alkylation Catalysts Based on Niobium Pentachloride

New active catalysts based on niobium pentachloride immobilized on the surface of silica gel or aluminum oxide for the alkylation of aromatic compounds were prepared. The reaction occurs with a high rate at room temperature. Thus, the conversion of 1-hexene in the alkylation of benzene or toluene was close to 100% only 5 min after the onset of the reaction.

Highly enantioselective cobalt-catalyzed hydrogenation of 1,1-diarylethenes was developed by using bench-stable chiral oxazoline iminopyridine-cobalt complexes as precatalysts. A unique o-chloride effect was observed to achieve high enantioselectivity. Easy removal as well as further transformations of the chloro group make this protocol a potentially useful alternative to synthesize various chiral 1,1-diarylethanes. This process can be successfully performed under 1 atm of hydrogen at room temperature on gram scale.
