Versuchsvorschrift

To a solution of 1.9 mL (13.8 mmol) of dichloro(β-cyano)ethoxyphosphine in 40 mL of dichloromethane cooled in an ice-water bath was added 10 mL of diisopropylethylamine, followed by adding 2.3 mL (13.8 mmol) of diisopropylamine under Argon. The reaction b mixture was warmed up to room temperature and stirred for 2 h. After adding 0.1 gm of DMAP into the solution, the reaction mixture is ready for next step reaction.
