Anatomy of Ene and Diels-Alder Reactions between Cyclohexadienes and Azodicarboxylates
Jenner, Gerard,Salem, Ridha Ben
, p. 1961 - 1964 (1990)
In contrast with other (C...H...N) hydrogen transfers, the high-pressure kinetics of the ene reaction between cyclohexa-1,4-diene and diethyl azodicarboxylate show a concerted transition state.The discrepancy is assingned to the enhanced rigidity of the cyclohexadiene molecule with orthogonal hydrogen transfer to the nitrogen atom.Cyclohexa-1,3-diene reacts with diethyl azodicarboxylate according to a concerted Diels-Alder reaction.

The oxidation of diethyl 1, 2-hydrazinedicarboxylate using a catalytic Cu(II)-oxazoline system occurs at RT in air, resulting in azo generation, which can then be trapped in situ via hetero-Diels-Alder (HDA) and competitive ene-reactions, with chemoselect
A facile and convenient synthesis of 1,2,3,6-tetrahydropyridazines using azodicarboxylates under lanthanum triflate catalysis

The hetero-Diels-Alder reaction catalyzed by lanthanum triflate hydrate using diethyl azodicarboxylate as dienophile, yielding differently substituted 1,2,3,6-tetrahydropyridazines, is described.
