Calix[4]arenes Substituted on the Narrow Rim with Malononitrile and Cobalt Bis(dicarbollide) Anion

Original language description

Nitrile groups are suitable precursors for amino functions to which various other groups can be attached. Thus, the reaction of the 1,3-bis(3-bromopropyl ether) or 1,3-bis(4-bromobutyl ether) of tert-butylcalix[4]arene with methylmalononitrile has been studied in order to attach four nitrile groups to the narrow rim. Bimacrocyclic dinitriles were formed in 70% yield with malononitrile, and tetranitriles in 85% yield with methylmalononitrile. Subsequent alkylation of the tetranitriles with cobalt dioxane-bis(dicarbollide) gave dianionic calix[4]arenes, isolated as the cesium salts in 68% and 89% yield.
