Environmentally friendly oxidation of primaryaliphaticamines to imines has been successfully achieved, under metal-free conditions, by the use of diverse electrogenerated o-azaquinone mediators. High catalytic performance, together with high chemoselectivity, were observed with electron-poor o-azaquinone catalysts generated from 2-aminoresorcinol derivatives. Similar to copper amine oxidase enzymes, these
The scope and mechanism of an electrochemically induced cascade reaction, which leads to highly substituted 1,4-benzoxazine derivatives, have been explored through the variation of the structure of the o-azaquinone mediator. This reaction sequence, wherein both cycloaddition partners are generated in situ, at room temperature, under metal-free conditions, allows the regiospecific inverse-electron-demand
