A STUDY OF NEW RHODIUM COMPLEX WITH CARBORANE LIGAND

The complex [closo-3,3-(PPh_3)_2-3-H-3,1,2-RhC_2B_9H_(11)]has a rich derivative chemistrythat is currently under active investigation.The resultant compound shows an increasing stabilitythat is often associated with metallocarboranes.This paper deals with the novel and the produc-tion area of carborane complexes of transition metals.The paper indicates that some reactions can easily proceed and the resulting compound hassome new properties and uses.K[18-crown-6][closo-3-Ph_3P-3-CH_2Ph-3-Br-3,1,2-RhC_2B_9H_(11)]can be synthesized by the reaction of K[18-crown-6][(Ph_3P)_2RhC_2B_9H_(11)]withbromo-toluene under the condition of dry benzene.IR and ~1H,~(11)B,~(31)p nuclear magnetic reso-nance and elemental analysis comfirm the structure for this species with one carborane groupbonded to the central metal.
