  Transmetalation from boron to rhodium in the absence of basic activators is reported to proceed by beta-aryl elimination from a series of triethylphospine-ligated rhodium(I) arylboronates and diarylborinates. [Rh(PEt3)(3)OB(OH)Ar] were prepared by treating Rh(PEt3)(2)[N(SiMe3)(2)} with the corresponding arylboronic acid, ArB(OH)(2), in the presence of added PEt3. One example of these complexes was characterized by X-ray diffraction. [Rh(PEt3)(3)OB(mesityl)(2)] and [Rh(PEt3)(2)OB(mesityl)(2)] were prepared by analogous methods from dimesitylborinic acid in the presence and absence of added PEt3. Heating of the trisphosphine boronate complexes in cyclohexane generated the rhodium aryl complexes, [(PEt3)(3)RhAr] and boroxin in good to high yields. [Rh(PEt3)(3)OB(mesityl)(2)] also underwent aryl migration to form [(PEt3)(3)Rh(mesityl)] and a cyclic boroxine. Kinetic studies showed that migration of more electron-poor aryl groups from the boronate complexes was slightly faster than migration of more electron-poor aryl groups and that migration of the o-anisyl group was particularly fast. Kinetic results are most consistent with a ligand dissociation pathway with a rate-limiting beta-aryl elimination from a 14-electron, bis(phosphine) intermediate.
