positions of the upperrim of di-O-propargyl-substituted calix[4]arene and p-tert-butylcalix[4]arene. The reduction of nitro group at the upperrim proceeds along with the depropargylation upon the addition of a nickel catalyst to the reaction mixture with hydrazine hydrate, which leads to calixarenamines containing free hydroxy groups.
