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...
