摘要：

The tetrabutylammonium (TBA) salt of [B12H12]2- reacts with 1,2,3-trichlorobenzene at 180-degrees-C, forming m,p,m-isomers of the hydrododecaboratanion: [1-(m,p,m-Cl3C6H2)B12H11]2- (1) and [1,7-(m,p,m-Cl3C6H2)2B12H10]2- (2). The aromatic rings are connected with the B-12-cage by C-B bonds. The compounds are characterized by B-11 NMR, C-13 NMR and H-1 NMR spectroscopy and by elemental analyses. The influence of different phenylsubstituents on the chemical shift of B-11, especially to lower field for the ipso-B atomes and by antipodal effect to higher field is discussed.
