Triazolines XVIII. Nickel peroxide oxidation of 4,5-dihydro-1H-1,2,3-triazoles bearing sterically crowded ortho-substituted 5-phenyl groups

Article abstract of DOI:10.1055/s-1990-26825

Nickel peroxide functions as an efficient oxidizing agent, superior to permanganate (phase-transfer catalytic system), in the oxidative dehydrogenation of 4,5-dihydro-1H-1,2,3-triazoles 1a-1, bearing sterically crowded ortho-substituted 5-phenyl groups, t
