Synthesis of Closo- and Nido-Metalloboranes from Metallocenes.

Abstract

Two general methods have been developed for the synthesis of nido- and closo-metalloboranes. The first method is termed nido-cage closure. The nido-borane species 'closes' around the metal atom of the metallocene reagent with expulsion of a cyclopentadienyl moiety. This process may occur with or without loss of molecular hydrogen or possibly by hydride transfer to the cyclopentadienyl ligand and has many precedents in metallocarborane syntheses. The second route to closo-metalloboranes may be classified as polyhedral expansion of closo-borane anions.
