Abstract

(Ally1oxy) methyl-substituted N,"-dibenzyldiaza-l8-crown-6 was prepared by five different processes. A simple Okahara ring closure of an (ally1oxy) methyl-substituted diazahexaethylene glycol proved to be the most convenient method. The corresponding N, N'-dihexyl-and N, N'-diethyldiaza-lB-crown-6 compounds were also prepared. These (ally1oxy) methyl-substituted crown compounds were covalently bonded to silica gel by ...
