solution gave phenyl-di-(3-sulfonatophenyl) phosphine. The structure was confirmed by a combination of 1H and 13C NMR spectroscopy. A pair of calix[4]arenes with a tertiaryphosphine group on one rim and a methoxy ethylene glycol group on the other were prepared and characterized. One had the phosphine moiety on the narrow rim, and the other had the phosphine on the wide rim. Structural characterization
