资源简介:

Cu(OTf)2-catalyzed selective arene C–H bond hydroxylation and nitration reactions of azacalix[1]arene[3]pyridines were achieved using KNO2 as an ambident O- and N-nucleophile under very mild aerobic conditions to yield functionalized azacalixaromatics. The reaction, which selectivity between hydroxylation and nitration was modulated by the reaction medium employed, proceeded through a Cu(II)–Cu(III)–Cu(I) mechanism.
