Aqueous chemistry of the metallocene [Cp2MoCl 2]BF4: Evidence of autocatalytic molybdenum(V) reduction in water

The aqueous chemistry of the air-stable Mo(V) metallocene [Cp 2MoCl2]BF4 (1) yields an unexpected autocatalytic reduction when water is added to an acetonitrile solution of 1. While 1 yields the expected stable Cp-Mo ligation and rapid chloride hydrolysis in water, a Mo(V) → Mo(IV) reduction to the metallocene Cp 2MoCl2 (2) was evident. Under acidic conditions (pH ～2) or trace amounts of water this reduction was slow enough to be monitored spectroscopically, and it is shown to be autocatalytic in aqueous 2. No reaction occurs when 1 and 2 are in the dichloride form in acetonitrile (i.e., no water). It is hypothesized that the added water serves two roles. First it initially reduces a small population of 1 to 2, and then as the aquated Mo(IV) metallocene, it catalyzes the reduction of the remaining Mo(V) in water. This is the first aqueous investigation of the Mo(V) metallocene, and it shows a novel and unprecedented autocatalytic reduction that is mediated by water.

NEW OBSERVATIONS ON DICYCLOPENTADIENYLMOLYBDENUM COMPLEXES DERIVED FROM DIMETHYL ACETYLENEDICARBOXYLATE. CRYSTAL STRUCTURE OF 5-C5H5)2MoOC(O)CH=CCO2CH3>

Addition of chloroform to a solution of (η-C5H5)2MoH2 and dimethylacetylenedicarboxylate (CH3CO2CCCO2CH3) in THF at 0 deg C gives two new complexes: (i) chloro-?-alkenyl (η5-C5H5)2MoCl and (ii) metallacyclic 5-C5H5)2MoOC(O)CH=CCO2CH3>.An X-ray diffraction study of the latter product revealed the presence of one water molecule per one organometallic molecule in the unit cell: space group P21, a 12.111(9), b 7.374(2), c 7.830(5) Angstroem, β 93.43(4) deg, Z = 2.The Mo-C bond length is 2.180(6) Angstroem.A mechanism involving an intramolecular elimination of CH4 from the initially formed insertion product (η5-C5H5)2MoH is proposed for its formation.
