Structural and reaction chemistry of the open chromocene bis(2,4-dimethylpentadienyl)chromium

The reactivity of the open chromocene Cr(2,4-C7H11)2 (C7H11 = dimethylpentadienyl) has been investigated and found to parallel that of metal allyl complexes, such as Ni(C3H5)2. Thus, exposure to an excess of dmpe (Me2PC2H4PMe2) or t-C4H9NC brings about naked chromium reactions , leading to the formation of Cr(dmpe)3 and Cr(CN(t-C4H9))6, respectively, in good yields. With amine hydrochlorides and dmpe, one pentadienyl ligand may be removed, leading to the paramagnetic, 16-electron complex Cr(2,4-C7H11)(Cl)(dmpe), which could also be prepared from CrCl2(dmpe)2 and 1 equiv of K(2,4-C7H11). Reaction of the monochloride complex with LiCH3 leads to the formation of the analogous methyl complex. Structural determinations are reported for Cr(2,4-C2H11)2 and Cr(2,4-C7H11)(Cl)(dmpe). For Cr(2,4-C7H11)2, an open-sandwich structure was found, with the average Cr-C bond distance being 2.163 (3) ?, comparable to the value of 2.169 (4) ? for chromocene. The structure has been refined to agreement indices of R = 0.040 and Rw = 0.053 in space group D44-P43212 (No. 96) with a = b = 8.090 (1) ? and c = 20.847 (3) ? for Z = 4. For Cr(2,4-C7H11)(Cl)(dmpe), an unsymmetric piano-stool geometry was observed, in which one phosphorus atom is located under the open edge of the pentadienyl ligand, while the chlorine atom and other phosphorus atom are located under the formally uncharged C(2) and C(4) atoms of the pentadienyl ligand. The structure has been refined to agreement indices of R = 0.063 and Rw = 0.056 in space group D2h15-Pbca (No. 61) with a = 12.578 (2) ?, b = 12.117 (2) ?, and c = 23.094 (5) ? for Z = 8.

NEW ISOCYANIDE COMPLEXES OF CHROMIUM DERIVED FROM ETHANOLIC SOLUTIONS OF CHROMIUM(II)

Treatment of ethanolic solutions of chromium(II) (which are derived from the reduction of CrCl3*6H2O solutions) with excess phenyl isocyanide in the presence of KPF6 affords the complex PF6.Under similar conditions, p-tolyl isocyanide yields
