Pd(II)-catalyzed oxidative Heck-type reaction of triarylphosphines with alkenes via carbon-phosphorus bond cleavage

A Pd(II)-catalyzed oxidative Heck-type reaction of triarylphosphines with alkenes via carbon-phosphorus bond cleavage was reported. Under the optimal reaction conditions, most reactions proceeded smoothly to give the expected coupling products in acceptable to high yields.

ELECTROPHOTOGRAPHIC PHOTORECEPTOR

An object of the present invention is to provide a charge transport material and an electrophotographic photoreceptor using the charge transport material, the charge transport material sufficiently satisfying characteristics conventionally desired for a charge transport material for an electrophotographic photoreceptor, specifically, the charge transport material having a good solubility in a binder polymer, allowing formation of a stable and high-concentration organic thin film therefrom, and having a high carrier mobility. To achieve the object, the present invention provides a tris(4-styrylphenyl)amine derivative represented by the following general formula (1): wherein R1 represents a methyl group or methoxy group, and R2 represents a hydrogen atom, methyl group, or methoxy group, provided that a case where R1 and R2 are a methyl group and R2 is at the meta-position is excluded; wherein 50% or more of geometrical isomers have three double bonds which are all trans.
