  亲核反应性。第七部分 甲磺酸某些不饱和酯的水解机理

  摘要：

  甲磺酸烯丙酯在碱水解时可提供相应的醇，而顺式和反式-丁-2-烯的1,4-二甲磺酸酯可产生高产率的丁-2-烯，这可能是通过1,4-消除作用形成的然后在硫磺下进行碱水解。该二酯仅在与对硝基苯酚和苯硫酚的钠盐反应时才给出取代的产物。简要讨论了乙烯基和炔基活化磺酸酯的方式。

  Cationic antimicrobial polymers have been synthesized by a bulk addition polymerization of a nucleophilic agent comprising two tertiary amines and an electrophilic agent that comprises two leaving groups and an aromatic ring between the leaving groups. The reaction solvent for the polymerization is chosen to allow precipitation of the cationic polymer at the polymerization temperature, thereby limiting molecular weight. Quaternization and polymerization occur concurrently. The cationic polymers can be highly active against Gram-negative and Gram-positive microbes, and/or fungi. The cationic polymers can also be non-hemolytic and non-cytotoxic at the effective concentration against the microbes.
