Photolysis of N-hydroxylamines of type in the presence of 1,4-dicyanonaphthalene (DCN) as an electron acceptor gave high yields of nitrones . Crude nitrones have been trapped by 1,3-dipolar cycloaddition reaction with dimethyl fumarate. Mechanistic pathways have also been discussed.
在1,4-二氰基萘(DCN)作为电子受体的存在下,N型羟胺的光解产生了高产率的硝酮。粗硝酮已通过与富马酸二甲酯的1,3-偶极环加成反应被捕集。还讨论了机械途径。
