  each of the complexes an undecorated cyclopentadienyl ligand is present whereas the partner cyclobutadiene or cyclopentadienone ligand bears four identical aromatic substituents (phenyl, p-tolyl, p-fluorophenyl, 2-thienyl or 2,2′-bithienyl). This range of substituents allows for detailed structural comparison between members of the families of sandwich complexes presented here, and with previously reported

  The reaction of bulky alkynes C2R2 with (η5-C5H5)Co(CO)(dimethyl fumarate) under microwave irradiation provides complexes of the type [(η4-C4R4)Co(η5-C5H5)] in good to excellent yields. This protocol represents a significant improvement over those reported previously. In particular, the formation of insertion products such as cyclopentadienones or cyclohexadienes can be avoided. In addition, because

• Microwave-Assisted Synthesis of Cyclopentadienyl–Cobalt Sandwich Complexes from Diaryl Acetylenes

  Sealed tube microwave dielectric heating of diaryl acetylenes with cyclopentadienyl cobalt dicarbonyl at elevated temperature in p-xylene provides access to metallocenes in both the cyclobutadiene (Ar(4)C(4)CoCp) and cyclopentadienone (Ar(4)C(4)(C=O)CoCp) families. When compared with the traditional thermal approach, the current method offers dramatically reduced reaction times and, especially with respect to cyclopentadienone complexes, increased yields. In the case of an especially bulky diarylacetylene the microwave approach allows access to a complex that cannot be readily obtained under traditional thermal conditions. An initial microwave-promoted Sonogashira coupling may be employed for in situ generation of the diarylacetylene, although lower yields of the metallocene complexes are ultimately obtained.
