  Preparation, structure and properties of triphenylphosphine rhodium aryloxides

  摘要：

  The reaction of Wilkinson's catalyst with NaOAr in toluene cleanly affords the corresponding aryloxide complexes Rh(PPh3)(3)OAr (1), In solution, 1. exists in equilibrium with PPh3 and the corresponding Rh(PPh3)(2)(pi-ArO) (2). The addition of HOAr shifts the equilibrium completely toward the corresponding adducts 2.2HOAr, due to hydrogen bonding between the oxygen atom of the pi-coordinated OAr ligand and two molecules of HOAr. Heating of 1a-d in toluene at 60-80 degrees C leads to the elimination ui HOAr with concomitant cyclometallation uf a phenyl ring of one PPh3 ligand, affording mixtures of 1, 2.2HOAr, a cyclometallated Rh complex and PPh3. At room temperature, a reverse reaction slowly occurs to give equilibrium mixtures of 1, 2 and PPh3. Complexes 1 readily react with water, CO and H-2, affording Rh-2(PPh3)(4)( mu-OH)(2),Rh(PPh3)(2)(CO)OAr (3) and HRh(PPh3)(3), respectively. The latter complex was also obtained when complexes 1 were treated with methanol. The structures of the phenoxide complexes 1 and 2.2PhOH and of p-nitrophenoxide complex 3 were established by X-ray diffraction. (C) 1998 Elsevier Science S.A. All rights reserved.
