Abstract: A task is to provide a method for producing a polycyclic aromatic aminophenol compound through a reduced number of steps at a low cost with high safety. The method for producing a polycyclic aromatic aminophenol compound includes the step of reacting a compound represented by the general formula (1) below and an aromatic amino compound with each other: Wherein n represents an integer of 1 to 8, Ar represents a benzene ring optionally having a substituent, or a naphthalene ring optionally having a substituent, each of R1 and R2 independently represents a hydrogen atom, a hydrocarbon group having 1 to 6 carbon atoms and optionally having a substituent, or an aromatic group optionally having a substituent, and R3 represents a hydroxyl group, a methoxy group, or a halogen atom.

Abstract: An electrophotographic photoconductor comprises an electroconductive substrate and a photoconductive layer formed thereon comprising as an effective component at least one pyrenylamine derivative of formula (I): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, w, j, k, l, m and n are specifically defined in the specification. Furthermore, a novel pyrenylamine derivative for use in the above electrophotographic photoconductor, an aldehyde compound, which is an intermediate for producing the pyrenylamine derivative, and methods of preparing the pyrenylamine derivative and the aldehyde compound are disclosed.

Abstract: A process for the preparation of arylidene dyes comprises the reaction of an aromatic amine with an enolate salt of a formylated active methylene compound in the presence of a sulfonyl halide compound. An enol sulfonate is postulated as a reactive intermediate in the reaction. The process gives high yields of products under mild reaction conditions and allows the use of aromatic groups containing substituents such as hydroxy that lead to side reactions and low product yields with previously known methods for making arylidene dyes.

Abstract: Para-substituted o-benzylphenols are prepared by reacting p-substituted phenols with benzylating agents in the presence of zeolites of the faujasite type at elevated temperature.

Abstract: A process for selectively producing ortho-alkylated aromatic amines in high selectivity relative to N-alkylated aromatic amines. The process comprises reacting an aromatic amine, having at least one hydrogen atom in a position ortho to the amine functionality, and an olefin under conditions sufficient to effect an alkylation reaction, in the presence of a zeolite catalyst which has been thermally pretreated by heating the catalyst to a temperature greater than about 500.degree. C. for a period ranging from 0.5 to about 10 hours while sweeping an inert gas over the heated catalyst to remove water and ammonia formed during the thermal treatment, and subsequently recovering the alkylated aromatic amine.

Abstract: A (trifluoromethyl)naphthalene which has been prepared by reacting a halonaphthalene with a trifluoroacetate salt in the presence of cuprous iodide and a dipolar aprotic solvent is recovered by (1) replacing the dipolar aprotic solvent in the final reaction mixture with an alkane containing 6-12 carbons, (2) heating the resultant slurry to a temperature sufficient to dissolve the organic ingredients, (3) allowing the inorganic ingredients of the slurry to settle, (4) decanting the organic layer, and (5) cooling to precipitate the (trifluoromethyl)naphthalene.

Abstract: In a process for preparing a (trifluoromethyl)napthalene by reacting a halonapthalene with a trifluoroacetate in the presence of cuprous iodide and a dipolar aprotic solvent and separating out the inorganic ingredients of the final reaction mixture in the recovery of the product, the cuprous iodide is recovered by washing the separated inorganic ingredients with an alcohol and a carboxylic acid and then with water to purify the cuprous iodide.

Abstract: A process for ortho-cyanation of phenols or phenylamines which comprises reacting a phenyl compound having hydroxy or optionally substituted amino or cyclic amino, of which ortho position is vacant, with trichloroacetonitrile, C.sub.1 -C.sub.5 alkyl thiocyanate or C.sub.6 -C.sub.12 aryl thiocyanate in the presence of a boron trihalide and treating the resultant product with an alkali is provided, and said process is useful in the synthesis of intermediates for medicinals or pesticides.

Abstract: This invention relates to a process for producing ring alkylated aromatic amines. In accordance with this process an aromatic amine is reacted with an olefin, diolefin or an alcohol using a non-zeolitic molecular sieve as a catalyst. Under the conditions of the process the catalyst is extremely active, and with aromatic amines that are capable of alkylation at the ortho and para positions, high selectivity to the ortho alkylated isomer can be achieved.
