Synthesis, Characterization and Biological Activity of Some Haloorganophosphonates (III) Compounds

Three of the haloorganophosphonates (III) compounds of the chemical formula (CH3) 4N [RPCl2X], where R represents phenyl or propyl groups, and X represents Cl or Br were prepared. These compounds were characterized by I. R, atomic absorption, elemental analysis (CHN) techniques, and conductivity measurments. The biological activity of the prepared compounds was studied, they showed antimicrobial activity against three pathogenic bacteria viz, Staphylococcus aureus (gram positive), Escherichia coli, and Pesduomonsaeruginosa (gram negative). The effectiveness of these compounds was measured according to inhibition zone and colonies count methods.
