Abstract: Ectoparasitic insect pest controllers for animals, containing hydrazine derivatives of the general formula (I) as the active ingredient, and methods for application of the same: (I) [wherein A is (II), (III), (IV), (V) (wherein R4 and R5 are each H, C1-6 alkyl, or the like; and X is H, or one to five substituents selected from among halogeno and optionally halogenated C1-6 alkyl groups); R1 is H or C1-6 alkyl; R2 and R3 are each H, OH, C1-6 alkyl, phenylcarbonyl, or the like; Y is H, or one to five substituents selected from among halogeno, nitro, and cyano; Z is halogeno, cyano, C1-6 alkyl, or the like; and W is O or S]. The insect pest controllers exert remarkable controlling effects on parasitic insect pests harmful to domestic or pet animals, e.g. fleas, lice, ticks.

Abstract: A process produces an organic compound by allowing (A) a compound capable of generating a free radical to react with (B) at least one of esters and salts of nitrous acid in the presence of a nitrogen-containing cyclic compound constitutively having a skeleton represented by following Formula (i) in its ring: wherein X is an oxygen atom or an —OR group, and wherein R is a hydrogen atom or a hydroxyl-protecting group. Examples of the nitrogen-containing cyclic compound are cyclic imide compounds having a cyclic imide skeleton represented by following Formula (I): wherein n is 0 or 1; X is an oxygen atom or an —OR group, and wherein R is a hydrogen atom or a hydroxyl-protecting group.

Abstract: Oximes are prepared by reacting carbonyl compounds, hydrogen peroxide and ammonia in the presence of a catalyst system comprising a catalyst comprising titanium, silicon and oxygen and a cocatalyst comprising an acidic solid comprising an organic or inorganic support material, where either the support material itself has Lewis-acid or Brönsted acid properties, or Lewis-acid or Brönsted-acid functional groups are applied to the support material.

Abstract: A process for nitrosating C-H-acidic compounds. The process substantially avoids producing polluted wastewater.
