Dipolar Cycloaddition Reactions of Diazoazoles with Electron-Rich and with Strained Unsaturated Compounds

Regiospecific net 1,7-cycloaddition reactions of electron-rich or strained olefins and electron-donor acetylenes occur readily (-70 to -10 degC) with diazoazoles having nitrogen in the 2-positions of their azole rings.Diazoazoles such as 5-tert-butyl-3-diazo-3H-pyrazole (20), 3-diazo-5-phenyl-3H-pyrazole (24), 2-diazo-2H-imidazole (28), 4,5-dicyano-2-diazo-2H-imidazole (12), 4-diazo-4H-imidazole (63), 4-diazo-5-phenyl-4H-1,2,3-triazole (70), 5-cyano-4-diazo-4H-1,2,3-triazole (74), 3-diazo-3H-1,2,4-triazole (76), and 3-diazo-5-phenyl-3H-1,2,4-triazole (79) thus usually add effectively to unsaturated reactans such as enamines, 1-alkoxyalkenes, ketene acetals, aryl isocyanates, norbornene, and norbornadiene to give new 1,7-cycloadducts.These cyclization reactions may be followed by tautomerization processes leading to new stabilized fused heterocycles or by elimination to novel highly delocalized heteroaromatic derivatives. 4,5-Dicyano-2-diazo-2H-imidazole (12) undergoes various accelerated cycloadditions to unsaturates and adds to norbornene and norbornadiene by exclusive exo dipolar processes.Addition of activated acetylenes to representative α-diazoazoles also results in regiospecific 1,7-cyclization to give stabilized fused azolo heterocycles.

KINETICS OF REACTIONS OF 1,2,4-TRIAZOLES-3-DIAZONIUM IONS WITH PHENOL AND WITH HYDROXYL ION

5-Methyl and 5-phenyl-1,2,4-triazole-3-diazonium ions (IIIa, IIIb) react with undissociated phenol in diluted hydrochloric acid.At pH>1 the reactions with phenolate ions become kinetically significant, their bimolecular rate constants approaching those of

Higher Order Dipolar Cycloaddition Reactions of Diazoazoles with Electron-Rich Dipolarophiles

A study of the cycloaddition behavior of a series of diazoazoles with electron-rich dipolarophiles has been carried out. 3-Diazo-4-methyl-5-phenylpyrazole readily reacts with ynamines, enamines, and vinyl ethers to give 1,7-cycloadducts.The trisubstituted
