Jeans, Rebekah J.; Chan, Antony P. Y.; Murrell, Ashton H.; Chouman, Heather A.; Rosair, Georgina M.; Welch, Alan J. published the artcile< Metalation of Bis(meta-carborane)>, Application In Synthesis of 67421-02-7, the main research area is bicarborane metalation preparation metallacarborane ruthenium cobalt sandwich complex; crystal structure ruthenium cobalt sandwich bicarborane arene cyclopentadienyl complex; mol structure ruthenium cobalt sandwich bicarborane arene cyclopentadienyl complex.
The first metallacarborane derivatives of 1,1′-bis(meta-carborane) I [vertex = BH; 2, M = Ru(p-cymene), Z = H; 3, M = Ru(p-cymene), Z = OEt; 4, M = Ru(C6Me6), Z = H; 5, M = Ru(C6Me6), Z = OEt; 6, M = CoCp, Z = H; 7, M = Co(C5Me5), Z = H], have been prepared by deboronation of one cage and subrogation of the {BH} fragment removed by an isolobal {Ru(arene)}, {CoCp} or {CoCp*} fragment. In the case of the Ru(arene) species, attack on the products 2 and 4 by EtO- resulted in derivatives 3 and 5, resp., in which an OEt group is attached to B6 of the metallacarborane cage. All products were characterised by multinuclear NMR spectroscopy and single-crystal X-ray diffraction. All are of the form the 2,1,7-MC2B9-1′,7′-C2B10, and even though the structural studies reveal clear evidence of steric crowding between the arene or Cp/Cp* ligand on the metal and the pendant carborane cage, no isomerization of the metallacarborane to either 2,1,8-MC2B9 or 2,1,12-MC2B9 occurs, even on heating to reflux in toluene.
