  芳基和乙烯基碘的铜介导的二氟甲基化

  摘要：

  选择性氟化分子作为材料、药物和农用化学品很重要，但通过简单、温和的实验室方法合成它们具有挑战性。我们报告了一种直接的方法，用于将芳基和乙烯基碘与由现成的试剂产生的二氟甲基进行交叉偶联，以形成二氟甲基芳烃和二氟甲基取代的烯烃。电子中性、富电子和位阻芳基和乙烯基碘与 CuI、CsF 和 TMSCF(2)H 的组合反应导致高产率形成二氟甲基取代的产物，具有良好的官能团兼容性。这种转变令人惊讶，部分原因是先前观察到 CuCF(2)H 的不稳定性。

  Selectively fluorinated molecules are important as materials, pharmaceuticals, and agrochemicals, but their synthesis by simple, mild, laboratory methods is challenging. We report a straightforward method for the cross-coupling of a difluoromethyl group with readily available reagents to form difluoromethylarenes. The reaction of electron-neutral, electronrich, and sterically hindered aryl and vinyl iodides with the combination of Cul, CsF and TMSCF2H leads to the formation of difluoromethylarenes in high yield with good functional group compatibility. This transformation is surprising, in part, because of the prior observation of the instability of CuCF2H.

  Provided are multifunctional polymers comprising at least one anhydride repeating unit with at least one pseudo-cationic moiety graft and at least one hydrophobic graft. The grafting functionalizations can occur before, during, or after polymerizing the monomer(s). The anhydride employed may be partially or fully opened to provide amic acids, carboxylic acids, carboxylic acidic salts, imides, esters, and mixtures thereof. The polymers also may comprise other repeating units, including, but not limited to, alpha-olefins. In one embodiment the polymers exhibit antimicrobial activity, and can be employed in a wide variety of compositions, including those where antimicrobial activity is useful. A method of providing microbial activity also is provided.
