CH3NO2) mediated by [bis(trifluoroacetoxy)iodo]benzene (PIFA) is described. The NO2 transfer from CH3NO2 to the aromatic group of the substrate is possible with careful selection of the solvent, NaX, and oxidant. In addition, the solvent-controlled C(sp2)–H functionalization can shift to an α-C(sp3)–H functionalization (cyanation or oxygenation) of the α-C(sp3)–H of cyclic amines.
描述了由[双(三氟乙酰氧基)碘]苯(PIFA)介导的新型硝化作用(通过C(sp 3)–N破坏/ C(sp 2)–N与CH 3 NO 2形成)。的NO 2从CH转印3 NO 2到基板的芳族基团是可能的溶剂,的NaX,和氧化剂的仔细选择。此外,溶剂控制的C(SP 2)-H官能化可转移到一个α-C(SP 3)-H官能的α-C(SP的(氰化或氧合)3)-H的环胺。
