Reactions of bis[(2,3,5,6-eta)-bicyclo[2.2.1]hepta-2,5-diene]bis(mu-chloro)dirhodium, [RhCl-(NBD)]2, with bis- and tris(azolyl)methanes have been performed in methanol and acetone with 1:1 and 1:2 [RhCl(NBD)]2/ligand molar ratios. The structures of the complexes have been characterized by infrared and H-1 and C-13 NMR spectroscopy as well as X-ray diffraction analysis. Cationic species have been evidenced in the solid state while equilibria between cationic and neutral species have been established in solution.

Some 1,1'-diindazolylphenylmethanes have been prepared from indazoles and benzaldehyde in presence of zinc chloride as catalyst. The reaction was strongly dependent on the basic pKa 's of azoles and only few pyrazolyl derivatives could be prepared by this procedure. Extension of this method to other azoles was accomplished by using benzaldehyde dimethylacetal.

Abstract The cationic Cu(I) complex [Cu(N^N)2]+, where N^N is bis(indazol-1-yl)phenylmethane, was synthesized as chloride or tetrafluoroborate salt by reacting CuCl or [Cu(NCCH3)4][BF4] with bis(indazol-1-yl)phenylmethane under mild conditions. The structure of [Cu(N^N)2]Cl was ascertained by single-crystal X-ray diffraction. The complex exhibited bright yellow emission upon excitation with near UV
