A new organocatalytic and environmentally friendly aerobic oxidative‐catalyzed nitroso‐Diels‐Alder (NDA) reaction of N‐arylhydroxylamines with dienecarbamates has been developed. 3,6‐Bis(2,2,2‐trifluoroethoxy)‐s‐tetrazine was found to be an effective catalyst to selectively oxidize various N‐arylhydroxylamines in the presence of molecular oxygen, but in the absence of photostimulation, as a terminal
已开发出一种新的有机催化和环保的N-芳基羟胺与二烯氨基甲酸酯的好氧氧化催化亚硝基-Diels-Alder(NDA)反应。3,6-双(2,2,2-三氟乙氧基) -小号-tetrazine被发现是一种有效的催化剂选择性氧化各种Ñ -arylhydroxylamines在分子氧的存在下,但在没有光刺激的,作为终端氧化剂。此外,可以从市售的3,6-二氯四嗪中就地产生活性催化物质。
