| titleOfInvention | Process for the preparation of halogenoalkenes |
| abstract | In the process for the production of a halogenoalkene of the formula ##STR1## in which R 1 is an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aralkyl, aralkenyl or aryl radical or an optionally substituted heterocyclic radical, n R 2 represents a halogen atom, a cyano group, an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, aralkenyl, aryl, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl or aminocarbonyl radical or an optionally substituted heterocyclic radical, and n X is a halogen atom, n in which an α-hydroxy-phosphonic acid ester of the formula ##STR2## in which R 3 each independently is an alkyl or phenyl radical, or the two radicals R 3 together are an alkanediyl (alkylene) radical, n is reacted with a phosphorus-containing olefinating agent of the formula ##STR3## in which Z 1 is the phosphorus-containing radical ##STR4## R 4 and R 5 each independently is an alkyl, phenyl, alkoxy or phenoxy radical or together are an alkanedioxy radical, and n R 6 is an alkyl or phenyl radical, n in the presence of a base at a temperature between about -70° and +150° C., the improvement which comprises effecting the reaction in the presence of a halogen carrier. The end products are useful as intermediates such as in synthesizing pyrethroid-like insecticides. |
