Abstract

Reaction of Fc( S) PS2P( S) Fc and An( S) PS2P( S) An with NaOR [ R = Me, Et, Pr-i] gives the non symmetric sodium phosphonodithioate salts Fc( RO) PS2Na and An( RO) PS2Na respectively ( An = anisyl, Fc = ferrocenyl). These salts can be oxidised by I-2, activated by KI, to form organodithiophosphono disulfides of the type ( R( R'O) P( S) - S - S - P( S)( OR') R). Reactions of these salts with 2,4- dinitrosulfenyl chloride form organodithiophosphono disulfides of the type [ R( R'O) P( S) - S - S - R]. These sodium salts can also react with benzyl bromide to form S- alkyl O- alkyl 4- methoxyphenyldithiophosphonate esters and S- alkyl O- alkyl ferrocenyldithiophosphonate esters. All new compounds have been characterised spectroscopically and seven demonstrative X- ray structures are reported.
