MoF6 and WF6: Nonrigid molecules?

Calculations reveal that the octahedral-trigonal prismatic-octahedral rearrangement has particularly low-energy barriers for MoF6, WF 6, and (hypothetical) CrF6. Experimental evidence is obtained from the dynamic 19/

Synthesis and characterization of new alkoxide and aryloxide derivatives of titanium and zirconium. X-ray molecular structure of

Lithium or sodium alkoxides MOR (R = CH2CH-CMe2; M = Li 1; Na 2; R = C6F5; M = Li 3) were prepared by reaction of the alcohols with n-butyl lithium or sodium metal in hexane.Reaction of a hexane suspension of 3 with SiClMe3 afforded SiMe3(OC6F5) 4, whereas the reaction of 3 equivalents of C6F5OH with AlMe3 in hexane led to Al(OC6F5)3 5.Compounds 1 or 2 react with one equivalent of *Cl2Me> (Cp* = C5Me5) in toluene to give *ClMe(OCH2CH=CMe2)> 6.Complex 6 reacts with AlEtCl2 to give quantitatively *Cl3>.In the presence of water, the hydrolysis of 6 takes place giving the μ-oxo compound *Cl)(μ-O)>3>. *Cl2Me> reacted with an excess of the alcohol C6F5OH to give *(OC6F5)3> 7. reacted with two equivalents of pentafluorophenol in the presence of aniline to give the dialkoxide 8.When the same reaction was carried out in a 1:1 molar ratio, a mixture of 8 and the chloroalkoxide 9 was obtained.A clean reaction takes place when the μ-oxo compound is treated with two equivalents of pentafluorophenol, leading to the isolation of the alkoxo complex 2(μ-O)> 10.The methylalkoxo derivative 11, was obtained by reaction of with one equivalent of 3.Alternative methods can also be followed to synthesize 8 and 11.The crystal and molecular structure of 8 has been determined by X-ray diffraction methods.The most interesting feature of this structure is the disposition of the (C6F5) ring planes, which are located practically on the reflection plane defined by O(1), Zr(1) and O(1)'.

Phosphorus-fluorine chemistry. XXVII. Aryloxy-substituted fluorophosphoranes

The silyl ethers C6H5OSi(CH3)3 and C6F5OSi(CH3)3 undergo silicon-oxygen bond cleavage reactions with fluorophosphoranes, RnPF5-n (n = 0, 1, 2; R = CH3, C6H5, (CH3)2N in the case of C6H5OSi(CH3)3; n = 0, 1, 2; R = CH3, C6H5 in the case of C6F5OSi(CH3)3), to give a series of thermally stable compounds of the types (C6H5O)3-nPRnF2 and (C6F5O)3-nPRnF2 (n = 0, 1, 2). The intermediate (RO)2PF3, assumed in the reactions of PF5 with ArOSi(CH3)3, was isolated only in the form of the isomeric stable phosphonium salt [(RO)4P] [PF6]. The 31P and 19F nmr spectra of the new compounds are reported and discussed in terms of the structures of the molecules.
