Da. Buckingham et al., EQUILIBRATION OF CO(MECYCLEN)(S-ALAO)](2-[CO(MECYCLEN)(S-ALAO)](2+) ISOMERS VIA ONE-ENDED DISSOCIATION OF (S)-ALANINE() AND ANTI(ME)), Inorganic chemistry, 36(17), 1997, pp. 3791
Equilibration of the syn(Me)/anti(Me) isomers of [Co(Mecyclen)(S-AlaO)
](2+) in D2O is OD- catalyzed and occurs via opening up of the (S)-ala
ninato chelate and rechelation at an opposite octahedral face. This pr
ocess is preferred over the usually observed OD--catalyzed epimerizati
on at alpha-CHMe.
