hydrazination, followed by oxidative coupling of the obtained hydrazide. Ester groups with long alkyl chains or polyether increased the solubility of bisphenols in the epoxy resin. The epoxy resin was cured by heating with bisphenols in the presence of a catalytic amount of imidazole, with more rapid curing observed for more soluble bisphenols. The cured resin, with Td5 ≈ 300 °C, decomposed rapidly when exposed

Abstract Hypervalent iodine oxidation of p-substituted benzohydrazides (1a-h), phenylacetohydrazide (1i) and heterocyclic acid hydrazides (1j-I) using one equivalent of iodobenzene diacetate in dry dichloromethane or acetonitrile leads to dimerization thereby providing a new and facile method for the synthesis of N,N-diacylhydrazines 2.
