β-ketoimine calix[4]arenederivatives is described. The reaction of calix[4]arene or p-tert-butylcalix[4]arene with bromoacetonitrile or bromobutyronitrile afforded di-, tri-, and tetranitrile calixarene derivatives (3−8, 3a), which were then reduced into the corresponding amine (9−13, 3b). The condensation of these aminocalixarenes with acetylacetone led to six β-ketoimine calix[4]arenederivatives (14−18
