Abstract: In the prodn. of biaryl cpds. (I) by reacting esters (II) of an aromatic OH cpd. and a S oxo-acid (III) with a catalyst system (IV) of a Ni cpd. (V), a tert. aryl phosphine (VI), a metal salt (VII) and a reducing agent, the novelty is that (V) is a complex of NiC12 or NiBr2 and (VI); and (VII) is a Zn, Mn or alkali(ne earth) fluoride, chloride, bromide or salt of (III). (II) are pref derved from sulphonic, sulphinic, sulphenic, sulphuric or sulphurous ester, esp. aromatic sulphonic acids. (VII) is NaBr. USE/ADVANTAGE - (I) are useful as monomers for the prodn. of polyether-ketone and polyether-sulphones and as starting materials for the prodn. of optical whiteners, liq crystals cpds., polymer additives and dyestuffs. The process avoids the use of NaI in the catalyst system, avoiding discoloration of (I) by traces of I2.

Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are those of the general formula I I where R1, R2, R3 and R4 are each hydrogen or a non-ionic substituent, X and Y are each the radical of a methylene-active compound, or of an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic amine or hydrazine, and Z is hydrogen, methyl or phenyl, and the production of this recording medium.
