  Basicity of Secondary Penta-2,4-diynylamines and Their Reactions with Phenyl Isothiocyanate

  摘要：

  Secondary penta-2,4-diynylamines were synthesized, and their pK(a)(MeOH) values were obtained by means of nonaqueous potentiometric titration. The reactions of the amines with phenyl isothiocyanate, leading to 2-(phenylimino)-5-(prop-2-ynilidene)thiazolidines, were studied. The N-butyl- and N-benzylthiazolidines with alkyl substituents; at the triple bond, formed by the reactions, undergo autooxidation into thiazolidin-4-ones.

  Exploration of α,α-dibromo-β-dicarbonyl compounds as novel bromine agents for the conversion of alcohols to alkyl bromides under neutral conditions has been achieved. This method can be used for acid-sensitive substrates and allows the bromination of various primary and secondary alcohols to proceed at room temperature within a very short period of time.

  已经探索了作为新型溴化剂的α，α-二溴-β-二羰基化合物用于在中性条件下将醇转化为烷基溴化物的方法。该方法可用于酸敏感的底物，并允许各种伯醇和仲醇的溴化在非常短的时间内在室温下进行。
