The reaction of o-aminothiophenol with carbonyl compounds and t-BuNC was revisited and shown to provide 1-[1,3-benzothiazol-3(2H)-yl]methanimines (not described hitherto) and not the earlier reported 4H-benzo[1,4]thiazine. To isolate the latter using this reaction a due amount of caution and structure scrutiny is warranted. The basis for assignment of the products to both structural classes is provided.
我们重新研究了邻氨基苯硫酚与羰基化合物和 t-BuNC 的反应,结果表明这种反应生成了 1-[1,3-苯并噻唑-3(2H)-基]甲亚胺(迄今为止尚未描述过),而不是早先报告的 4H-苯并[1,4]噻嗪。要利用该反应分离出后者,必须谨慎行事,并对其结构进行仔细研究。本文提供了将产物归入这两种结构类别的依据。
