Application

4-Phenyl-1,2,4-triazoline-3,5-dione (PTAD) can be used as an efficient and selective reagent for the oxidation of thiols to disulfides.It can also be used:As a dehydrogenating agent to synthesize annulated dihydropyridazines by inverse [4+2] cycloaddition reaction between cyclic alkenes and 1,2,4,5-tetrazines.As a dienophile to synthesize cycloaddition products by fast hetero-Diels−Alder reactions.As an efficient oxidizing agent for the synthesis of pyridine derivatives from 1,4-dihydropyridines.In the synthesis of urazoles via [3+2] cycloaddition with allylsilanes.
