the poly(vinylether) gels resulted in a novel beaded polymer support with considerably improved as well as unique swelling characteristics in solvents ranging from hexane to water. The synthetic utility of the new gel was confirmed by carrying out a set of transformations with complete conversion leading to a useful amino and hydroxy terminated solid-phase precursor resin. Reaction progress could be

cotelomerization of vinylicethers VE (butyl vinylether and 2-acetoxy ethyl vinylether) with chlorotrifluoroethylene and mercaptans (2-hydroxy ethyl mercaptan and C6F13C2H4SH) are studied. The homo-telomerization of vinylicethers with these thiols and CCl3CH2OH leads to complex mixtures including acetals obtained by addition of the VE to hydroxy groups after telomerization of the thiol with the vinylether. Cotelomerization
研究了乙烯基醚VE(丁基乙烯基醚和2-乙酰氧基乙基乙烯基醚)与三氟氯乙烯和硫醇(2-羟基乙基硫醇和C 6 F 13 C 2 H 4 SH)的自由基共聚反应。乙烯基醚与这些硫醇和CCl 3 CH 2的均聚OH导致复杂的混合物,其中包括缩醛,该混合物是在硫醇与乙烯基醚进行端粒化后,通过将VE加至羟基而获得的。共聚单体化是相似的,但是我们还表明,巯基在所有带有乙烯基醚端基的自由基上的转移活性非常重要,几乎只能导致单加成消耗大量的巯基。因此,我们推断,在这些反应中,我们获得了共聚物(总消耗硫醇后形成)和这些低分子量加合物的混合物。
Tandem Reaction of Cationic Copolymerization and Concertedly Induced Hetero-Diels–Alder Reaction Preparing Sequence-Regulated Polymers
that the obtained copolymers had unprecedented 2:(1 + 1)-type alternating structures of repeating sequences of two VE and one furfural units in the main chain and one furfural unit in the sidechain. The specific DA reaction is attributed to the delocalization of the positive charge to the side furan ring.
展示了序列控制的阳离子共聚和位点特异性异-狄尔斯-阿尔德 (DA) 反应的独特串联反应。在糠醛和 2-乙酰氧基乙基乙烯基醚 (AcOVE) 的受控阳离子共聚中,只有与增长的碳正离子相邻的呋喃环与另一个糠醛分子的醛部分发生杂 DA 反应。共聚的另一个同样重要的特征是所获得的共聚物具有前所未有的 2:(1 + 1) 型交替结构,重复序列由主链中的两个 VE 和一个糠醛单元和侧链中的一个糠醛单元组成。特定的 DA 反应归因于正电荷离域到侧呋喃环。
