Abstract
Diaza-18-crown-6, K22, react with dichloroethane solvent to form a new Kryptand K22C2 with a bridge head. 13C NMR and UV spectra give further evidence of the formation of the new Kryptand. It was found that K22 dissolved in dichloroethane react with the solvent to form a new kryptand K22C2 and a precipitate form which was identified as the salt of K22C2.
