- Synthesis and Study of the Structure of Palladium(II) Acyclic Diaminocarbene Complexes Containing a 1,2,4-Oxadiazole Moiety
-
Abstract: The reaction of anilines containing a 1,2,4-oxadiazole moiety with thebis(xylylisocyanide) Pd(II) complex leads to the formation of acyclicdiaminocarbene complexes. The oxadiazole ring is not involved in the reaction.Composition and structure of the obtained complexes have been confirmed by meansof mass spectrometry, NMR spectroscopy, and single-crystal X-ray diffractionanalysis.

- 2-(1,2,4-Oxadiazol-5-yl)anilines Based on Amidoximes and Isatoic Anhydrides: Synthesis and Structure Features
-
Abstract: An efficient one-pot method was developed for the synthesis of 2-(1,2,4-oxadiazol-5-yl)anilines via the reaction of amidoximes with isatoic anhydrides in a NaOH–DMSO medium at ambient temperature. The method allows to obtain structurally diverse

- The role of the hydrogen bonding in cycloadditions of benzonitrile oxide with cyanophenols
-
The reactivity of aromatic nitriles in cycloadditions with benzonitrile oxide is remarkably enhanced by the ortho-hydroxy substituent. Semiempirical PM3 calculations are in agreement with a hydrogen bonding effect.

- Preparation of phenyloxadiazolylanilines
-
Phenyloxadiazolylanilines are prepared by reaction of a benzonitrile in an aqueous reaction medium first with hydroxylamine or an acid addition salt thereof to give a benzamideoxime and then with an isatoic anhydride to give a non-cyclic compound and subsequent cyclization, the reaction sequence being carried out in the presence of an anionic surfactant.

- Activation of Nitriles by Hydrogen Bonding in Cycloadditions with Nitrile Oxides
-
The dipolarophilic activity of aromatic nitriles in cycloaddition with benzonitrile oxides is remarkably enhanced by ortho-acylamino substituents.The activation depends upon the solvent and can be ascribed to a hydrogen bond which assists cycloaddition.
