The oxidation of secondary benzylic alchols to ketones by the chromium(VI) oxide/tert-butyl hydroperoxide system is compatible wih the presence of methyl, halide, methoxy, acetoxy or nitro substituents on the aryl group and of an unsaturation on the alkyl side chain. Benzyl alchol led to a mixture of benzaldehyde and benzoic acid.
Compounds of the general structure: Z - A - (S - B)n where A represents a linear aromatic molecular core, S represent a flexible spacer unit, B represents a crosslinking group such as a methacrylate group, n equals 1 to 3, and Z represents any entity compatible with the B groups, and in which A is a substantially aromatic nucleus containing fluorene ring structures substituted at the 9-position and in which the 9-positions of the fluorenes are not susceptible to oxidation.
