X-Ray Structural Studies of Stereoisomeric Bi(14H-dibenzo-diazepinoisoindol-14-ylidene)s obtained from the Reaction of 2,2'-Diaminobiphenyl with o-Phthalaldehyde

Reaction of 2,2'-diaminobiphenyl with o-phthalaldehyde yielded a number of products including two bi-(14H-dibenzodiazepinoisoindol-14-ylidene)s, (A) and (B); each was converted on heating into a third isomer (D).The crystal structure of (A), and that of (D), as the solvated trifluoroacetate salt were determined; (A), previously thought to be the trans-isomer, is in fact the cis-(R,R)/(S,S)-isomer (1a), a racemic compound, and (D) is the meso trans-(R,S)-isomer (2b).Compound (B) is considered to be the racemic trans-(R,R)/(S,S)-isomer (2a).The crystal structures of (A) and (D) and the 13C n.m.r. and u.v. spectra of all three isomers are discussed.
