The carbonyl-free, half-sandwich molybdenum(II) complexes CpMoCl(triphos) (1) and IndMoX(triphos) [X = Cl (2); I (3); triphos = Ph2PCH2CH2P(Ph)CH2CH 2PPh2; Ind = η5-C7H9 or indenyl] have been synthesized by either reduction of CpMoCl2 in the presence of triphos or by reduction and transmetallation of MoX3(triphos) (X = Cl, I) with CpNa or IndNa. The spectroscopic properties indicate a saturated, 18-electron structure in each case. All compounds are susceptible to oxidation in chlorinated hydrocarbons and the oxidation of 1 has been studied in detail both chemically and electrochemically. Compound [1]+PF-6 has been obtained by oxidation of 1 with AgPF6, whereas the corresponding AlCl-4 salt has been prepared in a one-pot reaction from CpMoCl2, triphos and AlCl3. The structure of 1 has been confirmed by X-ray crystallography as a four-legged piano stool with an η5-cyclopentadienyl ring and a tridentate triphos ligand. Copyright
