Conclusions

  1. 1.

    The nitration of 1- and 1′-phenyl-π-cyclopentadienyl-π-(3)-1,2-dicarbollyl cobalt complexes takes place in the para position of the benzene ring.

     
  2. 2.

    Action of the nitration mixture (HNO3:H2SO4 1∶3) on theπ-cyclopentadienyl-π-(3)-1,2-dicarbollyl cobalt complex leads to the formation of 8-nitrato-7r-cyclopentadienyl-π-(3)-1,2-dicarbollyl cobalt, reduction of which leads to 8-hydroxy-π-cyclopentadienyl-π-(3)-1,2-dicarbollyl cobalt.

     
  3. 3.

    The reaction of a mixture of CH3COCl and AlCl3 withπ-cyclopentadienyl-π-(3)-1,2-dicarbollyl cobalt leads to the formation of 8-hydroxy-7r-cyclopentadienyl-π-(3)-1,2-dicarbollyl cobalt.

     
  4. 4.

    9-Hydroxy-π-cyclopentadienyl-π-(3)-1,2-dicarbollyl cobalt was prepared from 9-hydroxy-o-carborane via 9-hydroxy-(3)-1,2-dicarboundecaborate.
