Rink酸树脂—4—(2′,4′—二甲氧基苯羟甲基)苯氧甲基聚苯乙烯的合成
-
摘要: 加入KI可使Linker(I)与氯甲基聚苯乙烯的反应时间大大缩短;在用NaBH4还原时加入金属卤化物增强其还原能力,制备出Rink酸树脂。Abstract: Ketone linker(I) was coupled to chloromethylated polystyrene via the addition of K 2CO 3 instead of the expensive Cs 2CO 3, and the reaction time was reduced greatly by addition of a little KI; ketone resin(II) was reduced by NaBH 4 in THF adding AlC
