been investigated as a new reagent for the nitrosation of various substrates containing an amino functionality. Reactions took place in an aqueous solution of the reagent. The pH of the reaction mixture remained in the range 4.3-5. Thus, hydrazides were transformed to the corresponding acyl azides, and the reactions with arenesulfonyl hydrazines afforded arenesulfonyl azides. Treatment of aromatic
Na(3)Co(NO(2))(6)已被研究作为一种新型试剂,用于对各种含氨基官能团的底物进行亚硝化。反应在试剂的水溶液中进行。反应混合物的pH保持在4.3-5范围内。因此,将酰肼转化为相应的酰基叠氮化物,并且与芳烃磺酰基肼的反应提供了芳烃磺酰基叠氮化物。用Na(3)Co(NO(2))(6)处理芳族胺得到1,3-二芳基三氮烯,收率极高; 还观察到最初形成的重氮化合物与富电子芳环的偶联。由于与该试剂形成络合物,因此无法亚硝化脂肪胺。
