Abstract :

This review presents an overview of the reaction of 2, 4-bis (4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson��?s reagent) with ROH [R = Me, Et, iPr& But] to produce the non-symmetric (4-methoxy-phenyl)-phosphonodithioicacid acid which was complex to Ni(II) & Co(II) by green synthesis approaches that have advantages over conventional methods involving heat and chemical solvent associated with environmental toxicity. Most of the synthetic methods reported to date rely heavily on organic solvents. In the present approach, the compounds were synthesized solvent less and were characterized by 1H, 31P NMR, and Mass Spectroscopy. The nickel complexes are square planar and the cobalt complex octahedral. All the data correspond to what has previously reported. This new route saves time, cost, energy and it is environmental friendly synthesized. These compounds have been reported to have antibacterial properties.
