Pentamethylcyclopentadienyl rhodium complexes
We report syntheses and structures of pentamethylcyclopentadienyl (Cp?) rhodium(III) and rhodium(I) complexes. Dicationic rhodium(III) complexes, [Cp?Rh(bpy)(MeCN)](PF6)2 and [Cp?Rh(vbpy)(MeCN)](PF6)2 (bpy = 2,2?-bipyridyl and vbpy = 4-vinyl-2,2?-bipyridyl), were prepared by treatment of [Cp?Rh(MeCN)3](PF6)2 with bpy and vbpy, respectively. The monocationic rhodium(III) complex, [Cp?Rh(Me4phen)Cl]Cl (Me4phen = 3,4,7,8-tetramethyl-1,10-phenanthroline), was prepared by treatment of the chloride-bridged rhodium dimer, [Cp?RhCl2]2, with Me4phen. Two rhodium(I) complexes were synthesized via reduction of their rhodium(III) counterparts using two different methods: Cp?Rh(bpy) was produced via a new route involving treatment of [Cp?Rh(bpy)Cl]Cl with thallium formate in dry acetonitrile, whereas [Cp?Rh(Me4phen)Cl]Cl was reduced with Na(Hg) to give Cp?Rh(Me4phen). The colors of the Rh(I) complexes are attributable to relatively intense visible-region MLCT absorptions.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 3,4,7,8-Tetramethyl-1,10-phenanthroline, you can also check out more blogs about1660-93-1
