| Abstract | Dehydrogenation rates of four 4, 5-disubstituted 9, 10-dihydrophenanthrenes to the corresponding phenanthrenes by 10% palladium on charcoal for the substituents, H, OCH3, F and CH3, appear to be related to the size of the substituents. The preparation of three new phenanthrenes, viz. 4, 5-dichlorophenanthrene, 4, 5-difluoro- phenanthrene and 4, 5-bis(trifluoromethyl)phenanthrene, is described. Treatment of mesitylene with either 10% palladium on charcoal at reflux or 2, 3-dichloro-5, 6- dicyano-l, 4-benzoquinone gives an appreciable yield of mesityl(3â, 5â-xylyl)methane. © 1987 ASEG. |
