Sulfonyl

  1. Functional groups strongly affect amino acid LC-MS derivatization
    Systematic evaluation of derivatization agents for LC-MS amino acid analysis identifies isoquinoline-6-carboxylic acid NHS ester as optimal, achieving nanomolar sensitivity and long-term stability.
  2. Chemical recycling of hydrofluorocarbons by transfer fluorination
    Chemical recycling method converts hydrofluorocarbons into usable fluoride sources through transfer fluorination, enabling synthesis of diverse fluorinated molecules at industrial scale.
  3. Modular synthesis of CF3/CHF2 dihydroquinoline sulfonyl fluorides
    Modular synthesis of CF3/CHF2-substituted dihydroquinoline sulfonyl fluorides via [4+2] cycloaddition and sulfur(VI) fluoride exchange without transition metal catalysis.
