- 中文摘要: The conformational isomers endo- and exo-[Mo{h3-C3H4(CH3)}(h2-pyS)(CO)(h2-diphos)] (diphos: dppm = {bis(diphenylphosphino)methane}, 2; dppe = {1,2-bis(diphenylphosphino)ethane}, 3) are prepared by reacting the double-bridged pyridine-2-thionate (pyS) complex [Mo{h3-C3H4(CH3)}(CO)2]2(h1:h2:m-pyS)2, 1 with diphos in refluxing acetonitrile. Stereoselectivity of the methallyl, C3H4(CH3), ligand improves the formation of the exo-conformation of 2 and 3. Orientations and spectroscopy of these complexes are discussed.
