Charge Distribution Within 1,2-Dicarba-closo-dodecaborane: Dipole Moments of Its Phenyl Derivatives

Abstract

The dipole moment of 1,2-dicarba- closo -dodecaborane is oriented with the positive end towards the carbon atoms as follows from measurements on phenyl derivatives with variable substituents. Towards the phenyl group, the substituent 1,2-C 2 B 10 H 11 behaves as a weak electron acceptor.
