ABSTRACT:
Forming a 4-aminobiphenyl derivative arylamine compound, includes (i) providing a first disubstituted 4-aminobiphenyl compound; (ii) optionally formylating the first disubstituted 4-aminobiphenyl compound to form a bisformyl substituted compound where the first disubstituted 4-aminobiphenyl compound is not a bisformyl substituted compound; (iii) acidifying the bisformyl substituted compound to convert formyl functional groups into acid functional groups to form an acidified compound; and (iv) hydrogenating the acidified compound to saturate at least one unsaturated double bonds in the acidified compound.
