Original language description
Two ionic calix[4]arenes substituted at the narrow rim with an unpaired number (n) of cobalt bis(dicarbollide)(1-) anions (1-) (n = 1 and 3) and (4 - n) CMPO groups (3c, 4c) have been synthesized via a three-step procedure based on nitrile substituted calix[4]arene precursors. Conjointly with them, the compound with a paired ratio of the groups, where n = 2 and the same substituents are located in mutually adjacent 1,2-positions, is reported (5c). Another compound with the paired ratio, but from a widerim series (6c) (n = 2) was successfully prepared starting from calix[4]arenes substituted with two nitro functions and two -OH sites available for further modifications. The reaction steps included, a) O-alkylation of the hydroxy functions present on the same rim by the 1-dioxane derivative [8-O(CH2CH2)2O(+)-1,2-C2B9H10)-(1,2-C2B9H11)-3,3-Co] (2) used as the reactive building block resulting in the respective ionic nitriles (3a-5a) or nitro compound (6a); b) Reduction of the nitrile or
