Tert. aromatic amine useful as charge transport cpd. in electrophotography- prepd. by heating cupric acetate and zinc under protective gas and Ullmann condensation of aryl-amine and iodo-aryl cpd. in same reactor

摘要

Prepn. of a tert. aromatic amine (I) involves reacting mono- and/or di-arylamine(s) (II) with mono- and/or di-iodoaryl cpd(s) (III) in the presence of a base and with Cu as catalyst. The catalyst is first produced by thermal reaction of Cu(II) acetate and Zn at 120-140 deg C in a protective gas atmos., then reaction is carried out in the same reactor at 170-230 deg C, using K2CO3 as base.
