Participants

Procedure

10 g of 2,2-dimethyl-3-phenyl-2H-azirine and 10 g of 4-dipropylaminobenzaldehyde were exposed to light in 2 liters of benzene under an atmosphere of argon for 40 minutes with a mercury high-pressure lamp of 2000 watt in a ring-mantle vessel through an interposed filter fluid. The filter fluid contained 35 g of cupric sulfate pentahydrate per liter of water and had a layer thickness of 1 cm. Not only the reaction solution but also the filter solution were cooled during the exposure to light in that they circulated with aid of pumps through a heat-exchanger positioned outside the photoreactor. During the exposure to light the temperature of the reaction solution amounted to 26° C. measured outside the photoreactor.
