摘要
Irradiation of 2,6-dicyanopyridine 1-oxide (VIIa) in dichloromethane with > 290 mμ rays gave rise to 2,6-dicyanopyridine (VIIIa; 20%), 5-cyano-2-pyrrolecarbonyl cyanide (IXa) (20%), and an oxazepine (Xa) tentatively assigned as 2,4-dicyano-1,3-oxazepine (Aa; 35%). 4-Methyl-2,6-dicyanopyridine 1-oxide (VIIb) gave similar photo-products. The mechanism implied in these photochemical reactions has been discussed. © 1969.
