Enantiomers of 2,2'-Spirobichromenes: Energy Barrier for Thermal Racemization during HPLC on Tribenzoylcellulose
As a first case in the field of spirochromenes, the energy barrier for thermally reversible ring opening of 2,2'-spirobichromenes (Scheme) is measured by racemization of preparatively enriched enantiomers. In addition, this barrier is estimated via racemization during HPLC (Fig.) on tribenzoyl...
