Isomeric [2.2]metaparacyclophane quinhydrones

The two [2.2]metaparacyclophane quinhydrones 1 and 2 were synthesized. Structure, stereochemistry and charge-transfer absorptions are discussed.

Electron Donor-Acceptor Compounds, XXXVI. Quinones and Quinhydrones of the - und Metaparacyclophane Series

The isomeric quinhydrones 1 and 2 as well as the bis(quinone) 6 of the metaparacyclophane series were synthesized.Precursor of these products was the tetramethoxymetaparacyclophane 3 which was prepared via 4 and 5.X-ray structure analyses of 1, 3 and 6 are discussed with regard to the steric strain in these molecules and the donor-acceptor orientation in 1.Charge-transfer absorption of 1 and 2 are reported as well as circular dichroism of 1 which was separated into enantiomers. - Following an analogous route the isomeric quinhydrones 13 and 14 as well as the bis(quinone) 15 of the metaparacyclophane series were prepared.The difference in steric strain of the - in comparison to the metaparacyclophane series is discussed on the basis of an X-ray structure analysis of 13.Charge-transfer absorption of 13 and 14 are reported.
