P. Ballesteros et al., (2,5-NORBORNADIENE)RHODIUM(I) COMPLEXES WITH BIS(AZOL-1-YL)METHANE AND TRIS (AZOL-1-YL)METHANE, Organometallics, 13(1), 1994, pp. 289-297
Reactions of clo[2.2.1]hepta-2,5-diene]bis(mu-chloro)dirhodium, [RhCl-
(NBD)]2, with bis- and tris(azolyl)methanes have been performed in met
hanol and acetone with 1:1 and 1:2 [RhCl(NBD)]2/ligand molar ratios. T
he 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 equilibr
ia between cationic and neutral species have been established in solut
ion.
