Crystal and Molecular Structure of 10-Substituted 9-Anthracenones. Substituent Size as the Controlling Factor for the Nonplanarity of the Central Ring

Article abstract of DOI:10.1021/jo00038a011

MM2 calculations for a series of 10-R-9-anthracenones demonstrate an increase of the folding of the central ring with increasing size of the substituent.All the substituents considered prefer the pseudoaxial position except fluorine, which prefers the pse
