rac-1,2-Bis(phenylchlorophosphino)-1,2-dicarba-closo-dodecaborane(12) (1) reacts with four equivalents of sulfur at 185-190°C in undecane to give the cyclic anhydride of 1,2-bis(phenylthiophosphoryl)-1,2-dicarba-closo-dodecaboranyl(12)- dithiodiphosphinic acid (2). Under comparable conditions, 1-phenyl-chlorophosphino-1,2-dicarba-closo-dodecaborane(12) (4) and 1-phenyl-chlorophosphino-2-phenyl-1,2-dicarba-closo-dodecaborane(12) (5) react with sulfur to give 1-phenylchlorothiophosphino-1,2-dicarba-closo-dodecaborane(12) (6) and 1-phenylchlorothiophosphino-2-phenyl-1,2-dicarba-closo-dodecaborane(12) (7). Compounds 4-7 were characterized by 1H, 31P, 13C and 11B NMR spectroscopy and elemental analysis, and X-ray structure determinations were carried out on 1 and 7.
