A facile synthesis of 1,3,4-oxadiazoles and 1,3,4-oxadiazoles-d5 via [4 + 1] cyclization of ClCF2COONa with non-amine compounds containing amino groups is developed. Of note, this is the first time that halofluorinated compounds are used as C1 synthon to construct deuterated nitrogen-heterocyclic compounds. The current protocol features simple operation, readily accessible raw materials, wide substrate scope and valuable products

We report, herein, a palladium-catalyzed cascade comprising carbopalladation, 1,4-Pd-migration and C(sp2)?C(sp2) bond formation to construct a variety of bis-heterocyclic frameworks in a single operational step. The methodology provi
Pd(OAc)2 catalyzed C-H activation of 1,3,4-oxadiazoles and their direct oxidative coupling with benzothiazoles and aryl boronic acids using Cu(OAc)2 as an oxidant

The first direct oxidative coupling of 1,3,4-oxadiazoles with benzothiazoles has been accomplished using Pd(OAc)2 as a catalyst and Cu(OAc)2 as an oxidant. The similar combination of the catalyst and the oxidant has also been applied for direct arylation of 1,3,4-oxadiazoles with aryl boronic acids. Several novel oxadiazole derivatives have been prepared in high yields following both the methods.
