2Mg-KOMe ratio is low, the positions of the two TMEDA absorptions are reversed compared to those of free TMEDA. The absorptions approach one another as the ratio increases, coincide at a ratio of ca. 2, and approach those of free TMEDA at higher ratios.

This does not rule out exchange of sec-butyl groups, since exchange of RMg groups can be much faster than inversion. House, H. O.; Latham, R. A.; Whitesides, G. M. J. Org. Chem. 1967, 32, 2481.
