Diarylnitrilimines, derived by thermolysis of appropriate diaryltetrazoles, form (4+2)? cyclo-adducts with dipolarophiles of isodrin type, e.g. (1); the resulting 2-pyrazolines thermally rearrange into pyrazoles by hydrogen group transfer.Kinetic data for examples of this and related reactions are reported.
