Description
1, 3-Dipolar cycloaddition reaction of diazomethane to various 5, 6-disubstituted 2-norbornenes were investigated. All the adducts obtained were 1-pyrazoline derivatives. In the reaction of trans-5, 6-dicyano(or dicarbomethoxy)-2-norbornene, two isomers were isolated and the structures were determined by NMR analysis.<BR>Kinetic study in diethyl ether showed that the rate increased in the order, exo-cis > trans > endo-cis. And electron withdrawing substituents increased the rates. The field effect was suggested to explain these results.
