Reaction Steps

Small scale: Ethylene glycol (1 g, 16.1 mmol) was mixed with Triton B (40% in MeOH, 0.22 g, 0.53 mmol) and cooled in an ice-bath, while acrylonitrile (1.71 g 32.2 mmol) was added. The mixture was stirred at room temperature for 60 hours after which it was neutralized with 0.1 M HCl (0.6 cm3) and extracted with CH2Cl2 (80 cm3). The extracts were concentrated under reduced pressure, and the residue was Kugelrohr-distilled to give 3,3′-(ethane-1,2-diylbis(oxy))dipropanenitrile (1.08 g, 39.9%) as a light coloured oil, bp 150-170° C./20 Torr.
