Novel Metallacycle Complexes from Bis(oxazolinyl)pyridine−Rhodium(I) Species and Diynes
摘要:
The reaction of [Rh(coe)(2)Cl](2) (coe = cis-cyclooctene), bis(oxazolinyl)pyridine (pybox), and diynes (O(CH(2)Cequivalent toCCO(2)Me)(2) and PhCequivalent toCCH(2)OCH(2)Cequivalent toCCO(2)Me) gave new types of metallacycle complexes, which were analyzed by X-ray crystallography and showed catalytic activity for cycloaddition of diynes and several alkynes.
