Synthesis and characterization of dinuclear p-, m- and o-xylyl bridged complexes of molybdenum and tungsten. The crystal structures of μ-p-xylyl- bis(η5-pentamethyl-cyclopentadienyltri- carbonylmolybdenum) and μ-m-xylyl-bis(η5- pentamethylcyclopentadienyltricarbonyltungsten)
摘要:
The reactions of eta(5)-Cp*M(CO)(3)Na(M = Mo, W) with alpha,alpha '-p-, m- and o-dichloro-xylenes yielded p-, m- and o-xylyl bridged dinuclear complexes of eta(5)-Cp*M(CO)(3) in high yields. All of such new complexes are stable to air and water, even stable in dilute acids and bases. (C) 1997 Elsevier Science Ltd.
