SYNTHESIS AND CHARACTERIZATION OF DINUCLEAR P-, M- AND O-XYLYL BRIDGED COMPLEXES OF MOLYBDENUM AND TUNGSTEN - THE CRYSTAL STRUCTURES OF MU-P-XYLYL-BIS(ETA(5)-PENTAMETHYL-CYCLOPENTADIENYLTRICARBONYLMOLYBDENUM) AND MU-M-XYLYL-BIS(ETA(5)-PENTAMETHYLCYCL

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. [References: 13]
