Procedure
-
To a solution of ethyl 10-undecenoate (0.400 mL, 1.7 mmol), acrylonitrile (0.210 mL, 3.2 mmol) in anhydrous toluene (5.8 mL) at 70 °C under nitrogen, a solution of UltraNitroCat (3.4 mg, 0.005 mmol, 0.3 mol%) in toluene (0.5 mL) was dropwised over 1 h. The mixture was stirred at 70 °C under nitrogen for 3 hours. 1,4-Bis(3-isocyanopropyl)piperazine (0.5mol%, 5.0 mg) was added to the reaction mixture to deactivate the catalyst. The solvent was removed under reduced pressure to obtain a light yellow oil (0.37 g).
The crude oil was analyzed by gas chromatography. The reaction conversion rate of 1 and 2 were 69.3% and 6.3%, respectively. The selectivity ratio of 1 and 2 was 92 : 8.

Experimenter's Comments
-
Toluene was dried over molecular sieves 4A and degassed by purging with nitrogen before use.
Preparation of catalyst stock solution: UltraNitroCat (6.9 mg) was dissolved in dry degassed toluene (1.0 mL).
The reaction mixture was analyzed by GC.
