Efficient synthesis of 1, 3, 4-oxadiazole-2 (3 H)-one was achieved by CsF/18-crown-6
mediated 1, 3-dipolar cycloaddition of nitrile imine and 2.0 MPa of CO2. CsF/18-crown-6 …

5-Substituted-2-ethoxy-1, 3, 4-oxadiazoles were conveniently prepared through a one-pot
sequential N-acylation/dehydrative cyclization between ethyl carbazate and N …

A copper-catalyzed oxidative annulation of sydnones with perfluorocarboxylic anhydride for
the synthesis of 3-aryl-5-fluoroalkyl-1, 3, 4-oxadiazol-2 (3 H)-ones is developed. A diverse …

The extensive use of polyethylene terephthalate (PET)-based packaging materials has
increased the desire to focus on their recycling. In this study, a chemical depolymerization …

A novel KI-catalyzed synthesis of 1, 3, 4-oxadiazol-2 (3H)-ones from aryl hydrazines, α-
oxocarboxylic acids and CO2 was reported. This process could effectively utilize CO2 from …

A convenient and efficient route has been developed to synthesize 1, 3, 4-oxadiazol-2 (3H)-
ones from CO2, hydrazines and aryl or aliphatic aldehydes. Promoted by hypoiodite (IO−) …

The divergent synthesis of two different classes of azole derivatives using 5-amino-
substituted 2-methoxy-1, 3, 4-oxadiazoles as common substrates is reported. Depending on …

A series of 1, 3, 4‐oxadiazol‐2 (3H)‐ones were prepared by an efficient copper‐catalyzed
one‐pot reaction of arylhydrazides, arylboronic acids and DMF. Moderate to good yield of 1 …
