连二亚硝酸钠中的连二亚硝酸根离子 N
2O2−
2有顺反异构。反式异构体更常见,但顺式异构体也是可被制备的,反应性比反式异构体高。[1][2]
反式异构体
反式连二亚硝酸钠是无色的,可溶于水,不溶于乙醇和乙醚。[3][4]
制备
反式连二亚硝酸钠可以由亚硝酸钠被钠汞齐还原而成。[5][6][7]
- 2 NaNO2 + 4 Na(Hg) + 2 H2O → Na2N2O2 + 4 NaOH + 4 Hg
反式连二亚硝酸钠是在1927年由A. W. Scott首次合成的。它反应了亚硝酸酯、羟胺盐酸盐和乙醇钠。[4][8]
- RONO + NH2OH + 2 EtONa → Na2N2O2 + ROH + 2 EtOH
一种较早的方法由David Mendenhall于1974年发表,为一氧化氮 (NO)和金属钠在乙二醇二甲醚、甲苯和二苯基甲酮的反应。这种盐之后通过水提取。[9]
