2-叠氮基-N-(2-叠氮乙基)乙胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A suspension of sodium nitrate (13.4 g; 0.194 mol), oxalic acid (24.4 g; 0.194 mol) and N,N-bis(2-azidoethyl)amine LI (15 g; 0.097 mol) in DCM (300 mL) was stirred vigorously at r.t. for 2.5 h. Silica gel (20 g) and hexane (200 mL) was added to the reaction mixture and the resulting suspension was filtered. The solids were washed (1:1 hexane/DCM, 200 mL). The solvent was evaporated under reduced pressure to afford N,N-bis(2-azidoethyl)-N-nitrosoamine LII (15 g; 0.081 mol; 84% yield). the resulting suspension was filtered The solids were washed (1:1 hexane/DCM, 200 mL) The solvent was evaporated under reduced pressure
