Facile formation of bis(3-indolyl)methyl- arenes by iodine-catalyzed reaction of indole with alpha,alpha'-bis(arylmethylene)ketones and alpha-substituted arylmethyleneketones in dry ethanol

摘要

Bis(3-indolyl)methylarenes are obtained in good yield by reaction of indole with alpha,alpha'-bis(arylmethylene)ketones and alpha-substituted arylmethyleneketones in dry ethanol using catalytic amount of molecular iodine at room temperature.A plausible mechanism for formation of these products has been suggested.
