The syntheses and X-ray diffraction structures of water soluble copper( II ) compounds containing the Schiff base ligand 2-(2-pyridylmethyleneamino)benzenesulfonate (L â ),viz. the dinuclear bis-μ 1,1 -azido [CuL(μ 1,1 -N 3 )] 2 ( 1 ) and bis-μ ...
With the activation of P(OEt) 3 and I 2 , carboxylic acids can smoothly react with various primary and secondary amines, affording a series of amides, including peptides without racemization. 31 P NMR spectroscopy studies showed that carboxylic phosphoric...

A computational and conceptual density-functional study has been performed on various [3 + 1] complexes of both Re(V) and Tc(V). The fully optimized complexes chloro(3-thiapentane-1,5-dithiolato)oxorhenium(V) and...
Two mononuclear Re(v) complexes were synthesized using two different O, N, N coordinating Schiff base ligands. The X-ray structure and catalytic properties of the complexes are investigated and the electronic structure and absorption spectra were also...
