    • This invention provides a process for preparing alkyne intermediates used for making dendritic polymers. This process concerns alkyne compounds, useful as "clickable intermediates" to produce novel core reagents, branch cell reagents, surface group reagents, dendron reagents, oligomeric extender reagents, dendrimer core reagents, or dendrimer shell reagents suitable for preparing dendritic polymers, which comprises: 1) reacting acetylenic halides ( i.e. chlorides, bromides or iodides) or acetylenic mesylates/tosylates with 2-alkyl/aryl-2-oxazolines or oxazines to produce N-acetylenic-2-oxazolinium or 2-oxazinium cation salts; and 2) reacting N-acetylenic-2-oxazolinium or 2-oxazinium cation salts as catalytic reagents for the polymerization of 2-alkyl/aryl-2-oxazolines or 2-alkyl/aryl-2-oxazines; or 3) reacting propargyl tosylate or propargyl halides with 2-ethyl-2-oxazoline and then polymerizing to alkyne substituted poly(2-ethyl-2-oxazolines) with a degree of polymerization ( i.e. , dp=1-100); or 4) reacting propargyl tosylate with 2-ethyl-2-oxazoline (1:1) in the presence of sodium bromide or sodium iodide in acetonitrile to form N-propargyl-2-oxazolinium bromides/iodides, respectively; or 5) reacting 3-butyne-1,4-ditosylate in the presence of sodium iodide or sodium bromide in acetonitrile to form 3-butyne-1,4-dioxazolinium iodide or bromide, respectively.
    • 本发明提供了制备用于制备树枝状聚合物的炔烃中间体的方法。 该方法涉及可用作“可点击中间体”的炔基化合物,用于制备适用于制备树枝状聚合物的新型核心试剂,支链细胞试剂,表面试剂,树枝状试剂,低聚延伸剂试剂,树枝状聚合物核试剂或树枝状大分子壳试剂,其包括: 1)使炔基卤化物(即氯化物,溴化物或碘化物)或炔丙基甲磺酸酯/甲苯磺酸酯与2-烷基/芳基-2-恶唑啉或恶嗪反应,生成N-炔属-2-恶唑啉鎓或2-恶嗪鎓阳离子盐; 和2)N-炔属-2-恶唑啉鎓或2-恶嗪鎓阳离子盐作为用于2-烷基/芳基-2-恶唑啉或2-烷基/芳基-2-恶嗪的聚合的催化剂; 或3)使炔丙基甲苯磺酸酯或炔丙基卤化物与2-乙基-2-恶唑啉反应,然后聚合成具有聚合度(即dp = 1-100)的炔取代的聚(2-乙基-2-恶唑啉); 或4)在溴化钠或碘化钠存在下,在乙腈存在下,使甲磺酸炔丙酯与2-乙基-2-恶唑啉(1:1)反应,分别形成N-炔丙基-2-恶唑啉溴化物/碘化物; 或5)在碘化钠或溴化钠存在下在乙腈中的3-丁炔-1,4-二硫酸酯反应,分别形成3-丁炔-1,4-二氧杂环丁烷碘化物或溴化物。
