摘要：
A variety of primary alcohols are shown to be converted to the corresponding benzimidazoles in one pot by employing IBX and o-phenylenediamine in DMSO at room temperature. o-lodobenzoic acid is the end product of IBX, which is employed in 1.0 equiv. Arylmethyl bromides are also shown to be converted likewise to benzimidazoles in moderate yields in one pot, albeit at slightly elevated temperatures. (C) 2011 Elsevier Ltd. All rights reserved.
