摘要:
The reactions of the substituted tetramethylcyclopentadienes [C5Me4HR] [R = ethyl (1), n-propyl (2), i-propyl (3), cyclopentyl (4), cyclohexyl (5), 4-NMe2Ph (6)] with Mo(CO)(6) in refluxing xylene gave the corresponding dinuclear metal carbonyl complexes [eta(5)-C5Me4R](2)Mo-2(CO)(6) (7-11), while similar treatment of [C5Me4H(4-NMe2Ph)] (6) with Mo(CO)(6) afforded an unexpected product [(eta(5)-C5Me4(4-NMe2Ph))MoO2] 2(mu-O) (12). All the new complexes were fully characterized. The molecular structures of 7, 8, 11 and 12 have been determined by X-ray single crystal diffraction. (C) 2013 Elsevier B.V. All rights reserved.
