2,4-DIFERROCENYL-1,3-DITHIADIPHOSPHETANE 2,4-DISULFIDE - STRUCTURE AND REACTIONS WITH CATECHOLS AND [PTCL2(PR(3))(2)] (R=ET OR BU(II))

Reaction of ferrocene (or 1,1'-dimethylferrocene) with P4S10 yielded R 'P(S)S2P(S)R' (R' = ferrocenyl) (or the analogous dimethylferrocene sp ecies). This compound reacted with catechols to form R'P(S)O2C2 ring s ystems and with [PtCl2(PR(3))(2)] (R = Et or Bu(II)) to give [R'PS3Pt( PR(3))(2)]. The new compounds have been characterised spectroscopicall y with illustrative examples having been fully studied by X-ray crysta llography.
