Monofunctional or telechelic polyethylenes (PEs) carrying phosphonic acid end groups are obtained from functional PE produced by catalyzed chain growth (CCG) on magnesium. CCG is first used to produce iodo‐end‐functionalized PE (PE‐I) that is efficiently turned into phosphonate end‐functionalized PE (PE‐P(O)(OEt)2) in the presence of triethylphosphite through the Michaelis–Arbuzov reaction. A simple treatment of the resulting PE‐P(O)(OEt)2 with bromotrimethylsilane leads to the targeted phosphonic acid end‐functionalized PE (PE‐P(O)(OH)2) for the first time. Vinyl‐end‐functionalized analogs (Vin‐PE‐P(O)(OEt)2) are produced using vinyl‐end‐functionalized PE‐I (Vin‐PE‐I) recently obtained through CCG. A cross‐metathesis reaction is then employed to couple Vin‐PE‐P(O)(OEt)2 and produce after treatment with bromotrimethylsilane the corresponding unprecedented α‐ω‐(diphosphonic acid) telechelic PE ((OH)2(O)P‐PE‐P(O)(OH)2).

带有膦酸端基的单官能和远螯聚乙烯
带有膦酸端基的单官能或遥螯聚乙烯(PE)是从在镁上催化链增长(CCG)产生的功能性PE中获得的。CCG首先用于生产碘末端官能化的PE(PE-1),在存在亚磷酸三乙酯的情况下,通过Michaelis-Arbuzov反应将其有效地转变为膦酸酯末端官能化的PE(PE-P(O)(OEt)2)。 。用溴代三甲基硅烷对所得的PE-P(O)(OEt)2进行简单处理,首次得到了目标膦酸末端官能化的PE(PE-P(O)(OH)2)。乙烯基末端官能化类似物(Vin-PE-P(O)(OEt)2)是使用最近通过CCG获得的乙烯基端基官能化的PE-1(Vin-PE-1)生产的。然后使用交叉复分解反应偶联Vin-PE-P(O)(OEt)2并用溴代三甲基硅烷处理后产生相应的前所未有的α-ω-(二膦酸)远螯PE((OH)2(O)P -PE-P(O)(OH)2)。
