Abstract:
A process for producing a cis-3,7-dimethyl-2,6-octadienylamine compound represented by general formula (3): wherein R1 and R2 each represents a hydrogen atom or an alkyl, aralkyl, or aryl group having 1 to 10 carbon atoms, containing from 2 to 10% by weight cis-3,7-dimethyl-2,7-octadienylamine compound represented by general formula (4): wherein R1 and R2 each represents a hydrogen atom or an alkyl, aralkyl, or aryl group having 1 to 10 carbon atoms, which comprises subjecting a mixture of an alkylamine and isoprene in a molar ratio of from 1:4 to 1:4.5 to telomerization at a reaction temperature of from 80 to 100Â° C. for from 2.5 to 3.5 hours in the presence of an alkyllithium catalyst and/or phenyllithium catalyst.
