  ppm催化剂负载下烯烃的铜电催化二叠氮化

  摘要：

  1,2-二胺基序普遍存在于天然产物、小分子药物和不对称合成催化剂中。过渡金属催化的烯烃二叠氮化已发展成为一种有吸引力的获得连位伯二胺的策略，但由于对某种烯烃类型的限制、化学氧化剂的频繁使用以及对高负载量的要求，仍然具有挑战性，特别是在实际应用中金属催化剂（1 mol％或以上）。在这里，我们报告了一种可扩展的铜电催化烯烃二叠氮化反应，其中 0.02 mol% (200 ppm) 的乙酰丙酮铜 (II) 作为预催化剂，没有外源配体。除了使用低催化剂负载外，电催化方法具有可扩展性，与广泛的官能团兼容，适用于α的二叠氮化，

  “Inverse Polyampholyte” Hydrogels from Double-Cationic Hydrogels: Synthesis by RAFT Polymerization and Characterization

  摘要：

  We present two novel, homologous, pyridine-based monomers, 2-(pyridin-2-yl)ethyl methacrylate (PyEMA) and (pyridin-2-yl)methyl methacrylate (PyMMA), which, despite their structural similarity, the former can be readily. thermolyzed to methacrylic acid, while the latter remains intact under the same conditions. This was most dramatically demonstrated in the present work, where PyEMA and PyMMA were randomly terpolymerized with a dimethacrylate cross-linker using reversible addition-fragmentation chain transfer polymerization to yield weakly double-cationic polyelectrolyte hydrogels of three different compositions which, upon thermal treatment, they were readily converted to polyampholyte hydrogels. While the parent double-cationic polyelectrolyte hydrogels exhibited a swelling response only to low-pH conditions, the daughter polyampholyte hydrogels presented swelling responses to both high- and low-pH conditions. Owing to the relative values of the effective pK(a)'s of the weakly acidic and weakly basic units, with the latter being lower than the former ("inverse polyampholyte" behavior), the swelling profiles of the daughter hydrogels were insensitive to polyampholyte composition.
