- 1,2,3-Selenadiazole-driven single family MSNCs of CdSe
-
Herein, 1,2,3-selenadiazoles were instantly prepared by hand grinding the reactants via a solventless process and tested for their ability to act as a source of selenium for the synthesis of CdSe magic-sized nanoclusters (MSNCs) with size below 2 nm. The

- Cyclization of the semicarbazones to 1,3,4-oxadiazole derivatives using ceric ammonium nitrate as oxidant
-
Cyclization of the semicarbazones to 1,3,4-oxadiazole using ceric ammonium nitrate as oxidant was studied. 2-Imino-1,3,4-oxadiazolines can be produced from semicarbazones, which undergo thermolysis to amides. Benzoic acid benzylidene hydrazide can also be cyclized to 2-methoxy-2-phenyl-1,3,4-oxadiazole in the presence of ceric ammonium nitrate and methanol.

- Reactions of diazoalkanes with isocyanates. Synthesis of imidazolidine-2,4-diones, oxindoles, and oxazolidinones
-
Thermolysis of a 5,5-dialkyl-Δ3-1,3,4-oxadiazolin-2-one in nitrobenzene containing an aryl isocyanate at 150 deg C affords a 1,3-diaryl-5,5-dialkyl imidazolidine-2,4-dione, an N-arylcarbamoyl-3,3-dialkyloxindole, and a 3-aryl-2-arylimino-5,5-dialkyl-1,3-oxazolidin-4-one.Those products arise from attack of a diazoalkane, generated in situ from the oxadiazolinone by thermal cycloreversion, on the isocyanate function.Two imidazolidine diones, three oxazolidinones, and 14 oxindoles were prepared.

- MULTINUCLEAR MAGNETIC RESONANCE AND RELATED STUDIES ON AZOMETHINE BORON COMPLEXES OF SEMICARBAZONES AND THIOSEMICARBAZONES
-
Synthetic and stereochemical features of some interesting boron complexes have been described.These three and four coordinated complexes have been prepared by the interaction of 2-isopropoxy-1, 3,2-benzodioxaborole with semicarbazones and thiosemicarbazones having the donor sets NOH and NSH in unimolar ratio and with semicarbazones and thiosemicarbazones having the donor sets HONOH and OHNSH in 1:1 and 2:1 molar ratios.Depending on the stoichiometry of the reactions, different moles of isopropanol are liberated and a variety of new boron azomethine complexes are obtained.On the basis of IR, (1)H NMR, (11)B NMR and (13)C NMR data plausible geometries have been proposed for the resulting derivatives, X-ray powder diffraction studies of a representative compound have also been carried out and the results show that adopts 'orthorhombic' type of lattice with unit cell dimensions; a= 10.84 Angstroem, b= 24.12 Angstroem, and c= 28.74 Angstroem.
