(1,2,3,4,5)Pentachloroferrocene reacts with butyl lithium and then MeSSMe to give FeCp (Cp=η⁵-C5H5) (1).By repeating this procedure, FeCp (2) and FeCp (3) can be obtained.A crystal structure determination of 2 shows the two SMe groups in 1,3-orientation.A number of unsymmetrical cymantrenylbis- and tris(thioethers) (4-6) was prepared in a similar manner from Mn(CO)3 or Mn(CO)3 (R=Me, Ph), respectively.The cymantrene selenoethers Mn(CO)3 (7-10) (R=Me, n=1, 2, 3; R=Ph, n=2) were also prepared.Key words: Sulfur; Selenium; Iron; Manganese; Cyclopentadienyl; Metallocenes
