摘要：

The oxidative heterocyclisation of aldehydes and o-phenylenediamine with nitrobenzene or dimethylsulfoxide impregnated on silica gel and irradiated with microwaves affords benzimidazoles in good yields and high purity. When UV irradiation is used as an energy source, the reaction is very slow. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
