摘要:
A process for the preparation of a substituted vinyl-cyclopropanecarboxylic acid ester of the formula ##STR1## in which R.sup.1 and R.sup.2 each independently is alkyl with 1-4 carbon atoms or halogen,R.sup.3 is halogen, phenoxy or phenoxy substituted by alkyl with 1-4 carbon atoms or by halogen,R.sup.4 is halogen or methyl, andn is 0, 1, 2, 3 or 4,comprising saponifying with alkali an ester of the formula ##STR2## in which R.sup.5 is alkyl with 1-4 carbon atoms,thereby to replace R.sup.5 by an alkaline salt group, and directly reacting such salt without intermediate purification with a benzyl chloride of the formula ##STR3## Advantageously the benzyl chloride is obtained by the gas-phase photochlorination of a compound of the formula ##STR4## the chlorination proceeding to about 25 to 75%, and the chlorination mass being employed directly without isolation.
摘要:
Substituted 3-(1,2-dibromo-alkyl)-2,2-dimethyl-cyclopropane-1-carboxylic acid esters of the formula ##STR1## in which R.sup.1 is halogen or optionally substituted phenyl or optionally substituted alkyl,R.sup.2 is hydrogen, halogen or optionally substituted alkyl, andY is the radical of an alcohol customary in pyrethroids, with the proviso that Y is a benzyloxy radical which is substituted by halogen and optionally substituted by at least one additional radical if R.sup.1 is halogen or methyl,which possess pesticidal properties. The acid moieties of such esters wherein R.sup.1 is optionally substituted phenyl are new compounds.

The esters are produced by reacting enantiomers of the acids with d- or 1-menthol are selectively crystallizing.
摘要:
A process for the monohalogenation of alkylbenzenes in the .alpha.-position is disclosed wherein an alkylbenzene reactant containing a hydrogen atom in the .alpha.-position is contacted with a halogen and the reaction mixture is withdrawn such that the amount of monohalogenated alkylbenzene formed is no greater than 33 mol percent in the reaction mixture. Also disclosed are novel monohalogenated alkylbenzenes of the formula ##STR1## in which R.sup.7 represents trifluoromethoxy, trifluoromethylthio or 2-perfluoropropyl or also, if R.sup.8 represents chlorine, represents trifluoromethyl and, furthermore, ifR.sup.8 and R.sup.9 represent trifluoromethyl, represents hydrogen,R.sup.8 represents hydrogen or also, if R.sup.7 represents trifluoromethyl or trifluoromethoxy, represent chlorine and also, if R.sup.7 represents hydrogen and R.sup.9 represents trifluoromethyl, denotes trifluoromethyl andR.sup.9 represents hydrogen and, if R.sup.7 represents hydrogen and R.sup.8 represents trifluoromethyl, denotes trifluoromethyl.
