Notes:
Oxidative Cleavage of Poly(o1-phenylenediselenide)Poly(o1-phenylenediselenide) is cleaved at the Se-Se bond by treatment with SOCl2 to give benzene-1,2-bis(selenenyl chloride) (2) and benzene-1,2-bis(selenium trichloride) (3), respectively. In the solid state 2 is dimerized by Se…Se bonds whereas 3 is monomeric having terminal as well as intramolecular bridging Cl atoms. Treatment of 2 with SbCl5 gives an ionic compound (4) with a dimeric cation exhibiting a weak Se—Se bond and SbCl6- as a counterion 3 reacts with W(CO)6 to give trigonal prismatic dicarbonyl bis(o1-phenylenediselenolato)tungsten (5).
