Anhydrous, dimeric vanadyl(IV) complexes of Schiff bases derived from [1+1] condensation of salicylaldehyde (or its derivatives) and anthranilic acid, have been synthesized from CH 3 CN and were characterized by elemental analysis, FTIR, EPR, absorption, TGA, cyclic voltammetry and room temperature magnetic susceptibility measurements. These complexes were found to be oxidized by air in polar...
A new general and selective strategy for the synthesis of (dihalomethylene)bisphosphonic acid (XYMBP) partial alkyl esters (PE) with high selectivity and purity has been developed. Preparation is started from selected XYMBP tetraesters using tertiary or secondary amines as dealkylating reagents leading to trialkyl or P,P′-dialkyl XYMBP PEs, respectively. The solid state structures are given for three...
