Cobalt ethylidyne complex

INS spectra are shown in Fig. 7.17. The peak positions, Table 7.9, are close to those in the HREELS of ethene on Pt(lll) (the predominant exposed crystal faces) [64]. The spectrum was modelled with a non-planar ethene (H-C-C-H dihedral 82.8°). Spectral changes as the temperature was raised were attributed to ethylidyne, CH3C, by comparison with the spectra of a cobalt ethylidyne complex ( 7.2.2.6).

Mannich-type condensation of 4,4, 4"-ethylidyne-tris(3-azabutane-l-amine) complex 220 with excess of paraformaldehyde, phosphine, and triethylamine gave cryptand 221 with an encapsulated cobalt ion (Scheme 12.78). The phosphine was partly oxidized in the course of reaction and structure of corresponding oxide 222 was established by X-ray analysis [208].
