Ortho-carborane, preparation

The breakthrough came with the discovery that the nido anion C 2B<)1 In p (an icosahedral fragment prepared by removal of a BI P unit from ortho-carborane l,2-C2BioHi2, by means of its reaction with sodium methoxide in methanol) could coordinate strongly to transition metal cations in a manner similar to the cyclopentadienide anion, (11 (Scheme 3.7)11.40,198-202... [Pg.124]

Zakharkin and co-workers have developed a method to attach a variety of substituents at B(3) of ortho-carborane. Using the acid chloride derivative, they were able to prepare new sigma-bonded derivatives as indicated in the following sequence (18). [Pg.305]
