Fahrmann, Jan; Hilt, Gerhard published an article in 2021. The article was titled 《Alternating Current Electrolysis as Efficient Tool for the Direct Electrochemical Oxidation of Hydroxamic Acids for Acyl Nitroso Diels-Alder Reactions》, and you may find the article in Angewandte Chemie, International Edition.Reference of N-tert-Butoxycarbonylhydroxylamine The information in the text is summarized as follows:
The acyl nitroso Diels-Alder reaction of 1,3-dienes with electrochem. oxidised hydroxamic acids is described. By using a.c. electrolysis, their typical electro-induced decomposition could be suppressed in favor of the 1,2-oxazine cycloaddition products. The reaction was optimized using Design of Experiments (DoE) and a sensitivity test was conducted. A mixture of triethylamine/hexafluoroisopropanol served as supporting electrolyte in dichloromethane, thus giving products of high purity after evaporation of the volatiles without further purification The optimized reaction conditions were applied to various 1,3-dienes and hydroxamic acids, giving up to 96 % isolated yield. The experimental process involved the reaction of N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3Reference of N-tert-Butoxycarbonylhydroxylamine)
N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3) belongs to anime. Large quantities of aliphatic amines are made synthetically. The most widely used industrial method is the reaction of alcohols with ammonia at a high temperature, catalyzed by metals or metal oxide catalysts (e.g., nickel or copper). Mixtures of primary, secondary, and tertiary amines are thereby produced.Reference of N-tert-Butoxycarbonylhydroxylamine
