Aminosulphur trifluorides are prepared by reacting a secondary amine with SF4 in a reaction solvent containing a selected tertiary amine to produce the aminosulphur trifluoride product and a liquid amine-HF adduct. Substantially no solid amine-HF adduct is produced and the process produces aminosulphur trifluorides, such as dialkyl, diaryl and arylalkyl aminosulphur trifluorides, in high yields.
三氟化氨硫的制备方法是在含有选定叔胺的反应溶剂中,使仲胺与 SF4 反应,生成三氟化氨硫产物和液态胺-HF 加合物。该工艺基本上不会产生固体胺-HF 加合物,而且能以高产率生产三氟化氨硫(如二烷基、二芳基和芳烷基三氟化氨硫)。
