containing a variety of functionalities such as halo, azido, and thiocyano, efficiently cleave aziridines and epoxides to the corresponding products in high yields. The cleavages are regio- and stereo-selective. The reactions are complete in 1 h at 60 °C and do not require any other catalyst or organic solvent. Thus, a convenient synthetic route to 1,2-haloamines, 1,2-azidoamines, 1,2-thiocyanoamines,
离子液体含有多种官能团,如卤素、叠氮基和硫氰基,能以高产率有效地将氮丙啶和环氧化物裂解成相应的产物。裂解是区域和立体选择性的。反应在 60 °C 下 1 小时内完成,不需要任何其他催化剂或有机溶剂。因此,开发了一条合成 1,2-卤胺、1,2-叠氮胺、1,2-硫氰胺、1,2-叠氮醇和 1,2-硫氰醇的简便合成路线。裂解、区域选择性、立体选择性
