本文介绍了通过非交联型两亲性无机配体的自组装过程制备的高活性和可重复使用的聚合物催化剂的开发。因此，以H3PW12O40和聚[(N-异丙基丙烯酰胺)-丙烯酰胺-铵盐共聚物]为原料制备的PWAA-1催化剂适用于醇、胺、硫化物在双氧水中的氧化反应。(NH4)2PdCl4与聚[(N-异丙基丙烯酰胺)1，0-二苯基膦苯乙烯]自组装生成的PdAs 2是一种在水、水-有机溶剂和有机溶剂中进行Suzuki-Miyaura反应的优良的可回收催化剂。它可以从东京嘉诚工业公司(TCI)获得。由(NH4)2PdCl4和聚[(N-异丙基丙烯酰胺)-5-二苯基膦苯乙烯]组装的PDAS-V3为Mizorogi-Heck反应提供了自身的循环体系。由钛(O-i-Pr)_4和聚(苯乙烯基-联二萘酸酯-共-苯乙烯)制成的TiSS_4作为可回收催化剂促进了不对称的羰基-烯反应。
I present herein the development of highly active and reusable polymeric catalysts produced by self-assembly process of non-cross-linked amphiphilic polymeric ligands with inorganic species. Thus, PWAA 1 prepared from H 3 PW 1 2 O 4 0 and poly[(N-isopropylacrylamide)-co-(acrylamide with ammonium salt)] is suitable for oxidation of alcohols, amines, and sulfides in aqueous hydrogen peroxide. PdAS 2 produced by self-organization of (NH 4 ) 2 PdCl 4 and poly[(N-isopropylacrylamide) 1 0 -co-diphenylphosphinostyrene] is an excellent recyclable catalyst for Suzuki-Miyaura reaction in water, water-organic solvent, and organic solvent. It is commercially available from Tokyo Kasei Kogyo (TCI). PdAS-V 3 assembled from (NH 4 ) 2 PdCl 4 and poly[(N-isopropylacrylamide) 5 -co-diphenylphosphinostyrene] provides recycling system of itself for Mizorogi-Heck reaction. TiSS 4 made from Ti(O-i-Pr) 4 and poly(styryl-linked binaphtholate-co-styrene) promotes an enantioselective carbonyl-ene reaction as a recyclable catalyst.
