1-Chloro-3,5,7-trimethyl-2,6-octadiene and a process for preparing it

摘要

The present invention relates to a new substance: 1-chloro-3,5,7-trimethyl-2,6-octadiene, and to a process for preparing it. The new compound, 1-chloro-3,5,7-trimethyl-2,6-octadiene, is of the following formula: CH3C(CH3)=CH-C(CH3)H-CH2-C(CH3)=CH-CH2Cl The process for preparing the compound indicated consists in that the methyl chloropentenes are reacted with isoprene in the presence of a catalyst, at a temperature from -50 DEG C up to +50 DEG C with subsequent isolation of the desired product. The product in question finds application in organic synthesis and as intermediate product for the synthesis of odorous substances.
