Abstract Isomerization of triallylamine in the system KOH-DMSO at 90-100° C leads to formation of tris-(1-propenyl) amine in quantitative yield. Under similar conditions, diallyl (ethyl) amine is converted into ethyl-bis (1-propenyl) amine, 1-ethyl-3-methylcyclohexane. Diallylamine in KOH-DMSO gives rise to a complexmixture of products consisting of bis (1- propenyl) amine, methylbis (1-propenyl) amine, 1-ethyl-3-methylcyclo-hexane, and 2-ethyl ...
