4-aminobiphenyl derivative arylamine compounds are formed by providing an iodinated organic compound; substituting the iodinated organic compound at carboxylic acid groups thereof to provide ester protecting groups; conducting an Ullman condensation reaction to convert the product of step (ii) into an arylamine compound; and conducting a Suzuki coupling reaction to add an additional phenyl group to the arylamine compound in the 4-position relative to the nitrogen.

A process or method for forming silane esters that is substantially free of oligomers. The process includes reacting an anhydrous salt of a carboxylic acid with a silane in a two phase reaction system. The silane comprises a halo-alkyl substituent. The two phase reaction system comprises a first solvent and a second solvent, wherein the second solvent is a solvent that is substantially non-miscible in the first solvent. An imaging member produced utilizing the silane esters so formed are also produced herein.

An aromatic silicon-containing compound has the formula:
Ar—[X-L-SiRn(OR′)3-n]m
where Ar represents an aromatic group, X represents a divalent or trivalent group; L represents a divalent linking group; R represents a hydrogen atom, an alkyl group or an aryl group; R′ represents an alkyl group having 1 to 5 carbon atoms; n is an integer of from 0 to 2; and m is an integer of from 1 to 5. The aromatic silicon-containing compound can be used in electrophotographic photoreceptors, particularly in outmost protective layers of such electrophotographic photoreceptors.
