Abstract
Coronands with two carbodiimide groups were prepared by the reaction of macrocyclic thioureas with triphenylphosphine in the presence of carbon tetrachloride and triethylamine. The reaction of these compounds with water, alcohols and amines afforded coronands containing urea, isourea and guanidine groups in high yields.Keywords
