The dehydration of two beta-hydroxyalkyl substituted 1,2-B10C2H12 carborane derivatives led to the formation of two new alkenyl substituted derivatives 1,2-3-Cyclopentene-1,2-dicarba-closo-dodecaborane 12 and 1,2-divinyl-1,2-dicarba-closo-dodecaborane 12. These products were degraded to the corresponding substituted 3-1,2-B9C2H12-1 dicarbollide anions and some representative transition metal derivatives prepared from them. The extent of alkenyl group participation in the derivative chemistry was investigated. It was found possible to directly observe an anionic pi-allyl substituted carborane derivative which was subsequently deuterated. Electronic spectra suggest the existence of conjugation in the alkenyl substituted dicarbollide anions. Author
