The 5H dibenzo (a and d) shikuroheputaniriden derivative and the 5H dibenzo (a and d) shikuroheputeniriden derivative, the manufacturing method and the electrophotographic photoreceptor null which uses

摘要

NEW MATERIAL:Compds of formula I (wherein X is -CH2CH2- or -CH=CH-; R1 and R2 are each an alkyl, an aralkyl, an arom. ring group or a heterocyclic group; R3 and R4 are each H, an alkyl or an alkoxy; Ar1 is an arom. ring group or a heterocyclic group). EXAMPLE:Compd. of formula II. USE:Org. photoconductive materials such as electrophotographic material, electronic plate, photosensor, etc., fluorescent brightener. PREPARATION:A 5H-dibeno[a,d]cycloheptane-5-one derivative of formula III and a 5H-dibenzo[a,d]cycloheptene-5-one derivative are reacted with a dialkyl phosphonate derivative of formula IV in the presence of a basic catalyst (e.g., NaOH) at room temp. to 100 deg.C. The resulting nitro compd. of formula 5 is reacted with a reducing agent (e.g., Na2SO4) to obtain an amino derivative of formula VI. The amino derivative is reacted with a halogen compd. of formula VII in the presence of a basic catalyst at 100-250 deg.C.
