Abstract

Abstract The reactions of 2-phenoxy-3, 5-dinitropyridine (1) with a series of substituted anilines (4a–d) in dimethyl sulfoxide (DMSO) in the presence of 1, 4-diazabicyclo [2.2. 2] octane (DABCO) yield the 2-anilino derivatives without the accumulation of intermediates. The kinetics is compatible with a two-step reaction involving initial nucleophilic attack followed by either base-catalyzed or uncatalyzed conversion to the product. The base- ...
