Synthesis, Spectral characterization and antimicrobial activity of 2-(substituted)-2,2-[1,3- dihydro-(3,4-1,2,5-oxadiazolediyl) diaza][5 , 5 -dimethyl-1 , 3 -propanediyl) dioxy] phosphoranes

The cyclic oxadiazolediyl dioxachlorophosphine precursor on subsequent reaction with various alcohols underwent halide displacement to give 2-substituted diaza phospholes. These phospholes on oxidative addition with di hydroxy alcohols form corresponding phosphoranes The antimicrobial activities of these compounds were evaluated and they exhibited significant antimicrobial activity.
