Abstract : Reaction of (closo-3,3-(PPh3)2-3-(H)-3,1,2-RhC2B9H11)(1) with sulfuric or nitric acid affords (closo-3,3-(PPh3)2-3-(HSO4)-3,1,2-RhC2B9H11)(2) or (closo-3-(PPh3)-3,3-(NO3)-3,1,2-RhC2B9H11)(3), respectively. Compound (3) can also be prepared from nitric acid and the dimeric metallocarborane ((closo-Rh(PPh3)(C2B9H11))2) or from NO2/N2O4 and (1). Complexes (2) and (3) have been used to prepared other new metallocarboranes. The reactions of these new metallocarboranes described herein are representative of interconversions carried out at a discrete transition metal vertex of a cluster species.
