Indium-Catalyzed Friedel-Crafts Alkylation of Monosubstituted Benzenes by 1-Bromoadamantane
摘要:
Indium salts such as InCl3 and InBr3 (ca. 1-5 mol%) efficiently catalyzed the Friedel-Crafts reaction of 1-bromoadamantane with benzene and monosubstituted benzenes to give 1-adamantyl benzenes. Indium bromide enabled faster reactions than indium chloride but the latter was more suitable in the case of halobenzenes.
