Optical stabilities of some oo′-bridged oo′-dichlorobiphenyls

Abstract

Racemisation parameters have been determined for 1,11-dichloro-5,7-dihydrodibenz[c,e]oxepin (1) and 1,11-di-chloro-6,7-dihydro-6,6-dimethyl-5H-dibenz[c,e]azepinium bromide (2). Their u.v. and c.d. spectra are discussed. Rotations of sodium 6,6′-dichlorodiphenate and 6,6′-dichloro-2,2′-bishydroxymethylbiphenyl are strongly temperature-dependent.
