Hydroxylamine and some of its derivatives, including hydroxamic acids, have been used as the amine component in Mannich-type condensation reactions with aldehydes and sulfinic acids or thiols. The condensation products have been oxidized to the corresponding nitroxides. The ESR spectra of these nitroxides are reported and interpreted in terms of the structure of these radicals. In several cases the
羟胺及其某些衍生物,包括异羟肟酸,已被用作与醛和亚磺酸或硫醇的曼尼希式缩合反应中的胺组分。缩合产物已被氧化成相应的氮氧化物。报告了这些氮氧化物的ESR光谱,并根据这些自由基的结构进行了解释。在某些情况下,ESR谱图显示出交替的线宽,并随温度和溶剂的变化而变化。
