The ionic liquid [bmim]Br as an alternative medium for the catalytic cleavage of aromatic C–F and C–Cl bonds
摘要:
The potential of [bmim]Br as an alternative to aprotic dipolar solvents in nickel-catalyzed hydrodehalogenation reactions is demonstrated. Hydrodechlorination of pentafluorochlorobenzene proceeds under the action of zinc in aqueous [bmim]Br. Under the above conditions aromatic C-F bonds also undergo slow cleavage. The reaction is significantly accelerated in the presence of nickel complexes with 2,2'-bipyridine or 1,10-phenanthroline. In the case of pentafluoroacetanilide highly regioselective ortho-hydrodefluorination leading to the formation of 3,4,5-trifluoroacetanilide is observed. (C) 2010 Elsevier Ltd. All rights reserved.

Aromatic amides bearing 2-azulenyl group on the amide nitrogen were synthesized and their structures were investigated. The π-electron density of the N-aryl group was found to influence the cis-trans conformational preferences of these compounds in solution. X-ray crystallography revealed that the plane of the 2-azulenyl ring has a strong tendency to lie coplanar with the amide plane when the azulene group

A nickel complex-catalyzed hydrodefluorination of acet(pentafluoroanilide) with zinc in ionic liquids resulted in the corresponding 2,3,4,5-tetrafluoro, 3,4,5-trifluoro, and 3,4-difluoro derivatives. The influence of the ionic liquid nature and the reaction conditions on its selectivity were studied, a possibility of the multiple reuse of the ionic liquids as the reaction media was demonstrated.
