Crownophanes possessing a pyridine moiety were prepared by means of intramolecular [2 + 2] photocycloaddition of the styrene derivatives. The crown compounds having six to ten ethereal oxygens selectively extracted Ag+ with high efficiency in the liquid-liquid extraction. The high extractability and efficiency were maintained even at low pH region of the extraction system. From ESI-MS analysis, it was found that the crownophanes formed some kinds of complexes having 1:1 and 2:1 stoichiometry (host/guest) with Ag+ and Pb2+ in MeCN-H2O homogeneous system.
SELECTIV BROMINATION OF THE AROMATIC RING IN ω-PHENYLPOLYOXAALKANES AND ALKANOLS IN MICELLES

The regioselecticity of bromination of ω-phenylpolyoxaalkanes and alkanols by bromine in aqueous solution of dodecyl sulfate (SDS) and aqueous solution of cetyltrimethylammonium bromide (CTAB) are shown to be related to the average orientation of substrate as indicated by 1H NMR studies.Thus ortho-bromination is promoted at higher concentrations of the surfactant relative to pure water.In contrast, at an equal ratio of the surfactant and substrate para-bromination is promoted.The results are discussed with respect to the average orientation of substrate in a micellar microenvironment and the formation of an ether-bromine comples as possible bromination agent.
