  Determining the Regioregularity in Alkyne Polycarbodiimides and Their Orthogonal Modification of Side Chains To Yield Perfectly Alternating Functional Polymers

  摘要：

  To understand the structure-property relationship in functional macromolecules through side chain modulation, both the accurate determination of the position of modifiable groups along the polymer chain and their subsequent modifications using high fidelity methods are crucial. In this report, the polymer microstructure of a helical alkyne polycarbodiimide has directly been probed through N-15 NMR spectroscopy on isotopic labeled poly(N-(3-ethynylphenyl)-N-15'-hexyl)carbodiimide and found to be a highly regioregular polymer structure. This polymer undergoes facile and quantitative CuAAC "click" chemistry, yielding perfectly alternating functional polymers. Advances have been made through the synthesis of new optically active alkyne polycarbodiimides with two independently modifiable pendant groups per repeat unit of polymers. Orthogonal postmodifications of the pendant groups were then performed to incorporate two different sets of small molecules in the repeat unit of polymers in a controlled manner and under mild reaction conditions using either sequential CuAAC "click" reactions when two dissimilar alkyne groups are present or a combination of CuAAC and thiol-ene click chemistries when pendant groups bear alkyne and vinyl moieties.

• Consecutive and Selective Double Methylene Insertion of Lithium Carbenoids to Isothiocyanates: A Direct Assembly of Four‐Membered Sulfur‐Containing Cycles
  作者：Raffaele Senatore、Monika Malik、Thierry Langer、Wolfgang Holzer、Vittorio Pace

  DOI：10.1002/anie.202110641

  日期：2021.11.15

  A formal CH2 -CH2 homologation conducted with C1 carbenoids on a carbon electrophile for the obtainment of a four-membered cycle is reported. The logic proposes the consecutive delivery of two single nucleophilic CH2 units to an isothiocyanate-as competent electrophilic partner-resulting in the assembling of a rare imino-thietane cluster. The single synthetic operation procedure documents genuine chemocontrol

  据报道，在碳亲电子试剂上用 C1 类胡萝卜素进行正式的 CH2 - 同系化以获得四元环。该逻辑提出将两个单一亲核 单元连续传递至异硫氰酸酯（作为有效的亲电伴侣），从而组装出罕见的亚氨基硫杂环丁烷簇。单一合成操作程序记录了真正的化学控制，如对装饰起始材料的各种反应元素的耐受性所示。值得注意的是，双重同源协议是直接在碳亲电子试剂上完成的，因此不需要安装以杂原子为中心的歧管（例如硼）。
• Synthesis of polymers having zwitterionic structure via the radical polymerization of 4-vinylphenyl isothiocyanate/cyclic amidine adduct

  A zwitterionic monomer (4‐vinylphenyl isothiocyanate [VPI]‐1,2‐dimetyl‐1,4,5,6,‐tetrahydropirimidine [DMTHP]) was synthesized by the reaction of VPI and a cyclic amidine DMTHP. A radical polymerization of VPI‐DMTHP was carried out using 2,2′‐azobis(2,4‐dimethyl‐4‐methoxy)valeronitrile (V‐70) as an initiator to give poly(VPI‐DMTHP). The obtained poly(VPI‐DMTHP) was not soluble in any of the investigated

  具有两性离子侧基的聚合物已发现了广泛的应用，例如杀真菌剂，阻燃剂，润滑油添加剂，乳化剂，防冻剂和电子材料。它们的性质不仅取决于聚合物主链，而且取决于两性离子结构。在本文中，描述了具有两性离子结构的新型聚合物的合成。通过VPI与环状am DMTHP的反应合成了两性离子单体（异硫氰酸4-乙烯基苯基酯[VPI] -1，2-二甲酰基-1,4,5,6，-四氢嘧啶[DMTHP]）。使用2,2'-偶氮二（2,4-二甲基-4-甲氧基）戊腈（V-70）作为引发剂进行VPI-DMTHP的自由基聚合，得到聚（VPI-DMTHP）。获得的聚（VPI-DMTHP）不溶于任何研究的有机溶剂，可能是因为它具有离子相互作用导致的网状结构。VPI-DMTHP和其他乙烯基单体（例如苯乙烯，甲基丙烯酸甲酯，合成了甲基丙烯酸叔丁酯和N-乙烯基吡咯烷酮。即使当VPI-DMTHP含量低（5 mol％）时，所获得的共聚物也不溶于所有检
