A series of novel tris-azolium salt precursors based on 1,3,5-
triphenylbenzene have been prepared. These salts exhibit fluorescence
emission in the 320−420 nm region. The coordination of these salts to
[MCl(COD)]2 (M = Rh, Ir) was carried out in the presence of KHMDS
and allowed the formation of the corresponding tris-NHC complexes of Rh
and Ir in high yield. The electronic properties of the new complexes were
analyzed by means of cyclic voltammetry and IR spectroscopy of the related
carbonylated species. The catalytic activity of the trirhodium complex
toward the addition of arylboronic acids to cyclohexen-2-one has been
evaluated and compared to the activity shown by a related monometallic
complex. [-]
