with other nucleophiles such as thiols, sulphinic acids, alcohols, and secondary amines at ca.–5 °C. Treatment of thionitrites with other thiols or sulphinic acids was found to yield the corresponding unsymmetrical disulphides or thiolsulphonates in good yields. Similar treatment of thionitrites with secondary amines or alcohols gave the corresponding N-nitrosoamines, or disulphides and nitrites.
通过硫醇与四氧化二氮(N 2 O 4)在温和条件下的反应,定量制备了芳基和烷基亚硫氰酸盐(RSNO)。通过在低温(例如0°C)下的红外光谱或紫外光谱或它们与亲核试剂的进一步反应生成已知的衍生物,鉴定出不稳定的亚硝酸盐。总结了这些亚硝酸盐的光谱数据,发现高反应性亚硝酸盐易于与其他亲核试剂,例如硫醇,亚磺酸,醇和仲胺,在约200℃下反应。–5°C。发现用其他硫醇或亚磺酸处理硫代亚硝酸盐可得到良好产率的相应的不对称二硫化物或硫代磺酸盐。用仲胺或醇类似地处理硫亚硝酸盐,得到相应的N-亚硝基胺或二硫化物和亚硝酸盐。
