  Electron capture negative ion and positive ion chemical ionization mass spectrometry of polychlorinated phenoxyanisoles

  摘要：

  AbstractSeveral polychlorinated phenoxyphenols with three to nine chlorine atoms were examined as their methyl ethers by electron capture negative ion and positive ion chemical ionization and electron impact mass spectrometry. In chemical ionization studies methane, hydrogen, nitrogen, helium and argon were used as reagent gases. Selected compounds were also examined with deuteriomethane, ammonia and deuterioammonia as reagent gases. Utilization of chemical ionization spectra in conjuction with electron impact spectra provides substantial structural information about these compounds. Chemical ionization spectra provide information about chlorine atom substitution. The position of phenoxy substitution can be established from electron capture negative ion and positive ion spectra.

  Several chlorophenoxy phenols were converted to their triflates by reaction with trifluoromethanesulfonyl chloride. The trifilates undergo triplet seneltlzed photolytic cyclizations at 300 nm in acetone to give chlorodibenzofurans or singlet state substitution reactions in carbon tetrachloride saturated with chlorine gas to give the corresponding chlorine substituted diphenyl ethers. 2-Chloro-3-hydroxy

  通过与三氟甲磺酰氯反应，将几种氯苯氧基苯酚转化为三氟甲磺酸。三氟甲磺酸盐在丙酮中于300 nm处进行三重骨架的光解环化反应，得到氯二苯并呋喃或在四氯化碳中被氯气饱和的单重态取代反应，得到相应的氯取代的二苯醚。类似地，将2-氯-3-羟基二苯并呋喃转化为2，3-二氯二苯并呋喃。氯取代三氟甲磺酸酯的机理似乎与氯-芳烃π络合有关。
