Versuchsvorschrift

A solution of 2,2'-(5-hydroxymethyl-1,3-phenylene)di(2-methylpropiononitrile), (1.9 g), in dichloromethane (20 ml) was treated with pyridinium chlorochromate (2.15 g) and stirred at room temperature for 1.5 h. The reaction mixture was subjected to flash column chromatography, eluting with dichloromethane, to give 2,2'-(5-formyl- 1,3-phenylene)di(2-methylpropiononitrile), mp. 145°-147°.

Aufarbeitung

  1. washeluting with dichloromethane
