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

Zakharkin, L. I.,Zhigareva, G. G.

, p. 1831 - 1833 (2007/10/02)

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.
