Soc., 84, 2499 (1962), could not be reproduced in the course of this study. Complexes (1) (L = CO) were prepared from NaCo(CO)4 and haloacetic acid esters in Et2O at 0–25°. Complexes (1) (L = MPh3) were prepared from (1) (L = CO) and MPh3 in n-hexane.

For type (3) compounds, a wide range of Co-X interaction strengths was detected frome.g. Y = CH2, X = H and cyclohex (no interaction) to Y = CH2, X = Ph or Y = CO, X = OPh (strong interaction),

The signal corresponding to the 3-CH2 group could not be observed in the spectrum of the BF3 adduct, most probably because of a spin-quadrupole interaction caused by the boron atom.
The adduct was prepared from Et2NCH2C CH and BF3OEt2 in CH2CI2 at room temperature.

EH and INDO calculations are in progress to test this hypothesis for type (1) and (2) complexes.

A separate series of experiments(20) demonstrated that Lewis acid-complex interaction does not take place at coordinated CO groups(21)) under the conditions we used.
