标 题 :Method of preparing tetrahalobenzene compounds, chemical intermediates used therein and certain of the compounds themselves
发明人：RICHARDSON PETER J
权利人:ICI LTD
摘要:Tetrahalobenzene compounds of the formula (I): ##STR1## in which X is independently chloro or, preferably, fluoro and Y is hydrogen or --N + R 3 A - in which each R is independently C 1-4 alkyl and A is a radical capable of forming an anion A - , are prepared by n (a) alkylating a compound of formula (II): ##STR2## or a salt thereof, to form a compound of formula (III): ##STR3## (b) treating the compound of formula (III) with a quaternizing agent of formula RA to form a compound of formula (IV): ##STR4## and (c) partially or completely reductively cleaving the compound of formula (IV) to replace one or both --N + R 3 A - groups by hydrogen. n Compounds (I), in which Y is --N + R 3 A - , (III) and (IV) are novel. Compound (I) is useful in the synthesis of insecticides.

标 题 :Process for the preparation of cyanotetrachlorobenzenes
发明人：MILNER DAVID J
权利人:ICI PLC
摘要:Cyanotetrachlorobenzenes, especially ortho- and para- dicyanotetrachlorobenzenes, are prepared by reacting in a liquid medium at 20 DEG -100 DEG C. a corresponding nitrotetrachlorobenzene with, in solution, an inorganic cyanide. Preferably the liquid medium is a two-phase water/water-immiscible organic solvent system, e.g. water/chloroform, a phase transfer catalyst is present and the inorganic cyanide is an alkali metal or alkaline earth metal cyanide. The compounds are useful chemical intermediates in the synthesis of, for instance, pesticidal compounds.

摘要:A composition comprising perfluoro-[2,2]-paracyclophane dimer compound is disclosed. The synthesis reaction of the paracyclophane dimer from 1,4-bis(chlorodifluoromethane)-2,3,5,6-tetrafluorobenzene involves heating in the presence of a metal catalyst and a solvent. A perfluorinated paraxylylene coating formed from the perfluorinated paracyclophane dimer is also disclosed.

摘要:Disclosed is a substituted cyanoaniline compound or a salt thereof, wherein the compound has a structure represented by General Formula I. The compound of General Formula I has broad-spectrum fungicidal activity in the field of agriculture and effectively prevents against a variety of pathogens such as cucumber downy mildew, wheat powdery mildew, maize rust disease, rice blast and cucumber gray mold. In particular, even at a low dose, the compound effectively prevents and treats rice blast, cucumber gray mold, maize rust disease and cucumber downy mildew. Moreover, the raw materials for preparing the compounds are widely available and the synthesis method therefor is simple and convenient.
