Charge Transfer alkyl metals

It is believed that the primary step involves excitation of the acyl complex via a metal-to-terminal CO charge transfer (755). The molecule then loses CO and rearranges to the carbonyl alkyl, as shown in Eq. (43). However, it... [Pg.111]

Hexaalkoxides are only known for the two elements tungsten and uranium. In both cases, physical and spectroscopic data are consistent with monomeric, octahedral complexes. Tungsten hexaalkoxides are pale yellow or colorless substances that readily sublime and exhibit the expected H NMR and mass spectra.189 The totally symmetric v(W—O) stretch occurs between 530 and 600 cm-1 in the IR spectrum, depending on the alkyl substituents. In contrast, the homoleptic phenoxide W(OPh)6 is intense red in color due to the presence of a strong oxygen-to-metal charge transfer band in this d° complex which absorbs in the visible part of the spectrum.36... [Pg.347]
