Article abstract of DOI:10.1246/cl.1986.1619

The population ratios +/-sc/ap in 9-(aryloxymethyl)-1,4-dimethyltriptycenes were determined by (1)H NMR spectroscopy.Whereas electron-withdrawing substituents favor the ap rotamer , electron-donating substituents favor the +/-sc rotamer in a relative sens
