PURPOSE:To obtain a new aminebiphenyl derivative useful as an intermediate for triarylamine compounds useful as organic photoconductors. CONSTITUTION:An aminobiphenyl derivative of formula I (R<1> is H, lower alkyl, lower alkoxy, aralkyl or halogen; Ar1 is phenyl, biphenyl, furyl, thiophenyl, thiazole, 1,3-dioxaindane or oxazole), e.g. a compound of formula II. This compound of formula I is obtained by reacting a halogenated biphenyl compound of formula III with an amino compound of the formula Ar1-NH2 in the presence of a transition metal catalyst or the transition metal catalyst and a basic substance or reacting the halogenated biphenyl compound of formula III with an acetyl compound of the formula Ar1-NHCOCH3 in the presence of the transition metal catalyst or the transition metal catalyst and a basic substance and then hydrolyzing the reactional product. |
