Abstract:
The reactions of K[(CF3)3BNC] and K[(CF3)3BCN] with (PPh3)3RhCl in ethanol resulted in the rhodium(I) complexes (PPh3)3RhNCB(CF3)3 and (PPh3)3RhCNB(CF3)3, respectively. Their 15N-labeled isotopomers were synthesized from the corresponding borate anions. The complexes were characterized by UV, Raman, and multi-NMR spectroscopy, and the crystal structures were obtained. The spectroscopic and structural data are compared to those of the potassium borates and to related rhodium(I) complexes.
