PRODUCTION OF 1,1-DICHLORO-1-ALKENES BY THE ACTION OF ALKYLMAGNESIUM HALIDES ON 1,1,1-TRICHLORO-2-PROPENE

The synthesis of 1,1-dichloro-1-alkenes was realized by the reaction of alkylmagnesium halides with 1,1,1-trichloro-2-propene. 2-Methyl-7-octadecyne, which is the main starting compound in the synthesis of Z-7,8-epoxy-2-methyloctadecane (Disparlure - the sex pheromone of Porthetria dispar), was obtained from 1,1-dichloro-1-dodecene.

Process for the preparation of halogen butenyl acrylates

Halogenbutenylacrylates of formula STR1 in which R represents hydrogen or C1 -C4 alkyl and X represents halogen may be produced by reacting an acrylic acid salt of formula STR2 wherein M is ammonium, alkali metal or alkaline earth ion, with 1,4-di-halogen-butene-(2) in a diphasic system.
