Reactions of the title compounds with trichloroacetic acid, in the absence and presence of water, have been studied by n.m.r. spectroscopy. Most of the products have been identified, and mechanisms are suggested which involve initial protonation on oxygen followed by steps that are determined by the various nucleophiles present. Under dry conditions, the nitrone isomerises to the O-ether. Under most
通过NMR光谱研究了标题化合物与三氯乙酸在无水和有水存在下的反应。已经鉴定出大多数产物,并提出了涉及在氧气上初始质子化然后由存在的各种亲核试剂确定的步骤的机理。在干燥条件下,硝酮异构化为O-醚。在大多数条件下,硝酮形成NN-双-甲基-硫代甲基羟胺。与干燥的氯化氢的反应已经简要地进行了研究。
