New polymer-supported organosilanes have been prepared using two different strategies. These involved the synthesis of soluble and insoluble supports through the copolymerization of styrene and monomers containing a thiophene ring. Selective metallation of the thiophene ring followed by silylation allowed the introduction of various functionalized organosilanes onto the polymer with a high degree of
已经使用两种不同的策略制备了新的聚合物负载的有机硅烷。这些涉及通过苯乙烯和含有噻吩环的单体的共聚来合成可溶性和不溶性载体。噻吩环的选择性金属化和随后的甲硅烷基化允许将各种官能化有机硅烷引入到具有高取代度的聚合物上。这些载体可用于固相有机合成,产物通过 Tamao-Fleming 氧化释放,在裂解过程中与回收载体一起产生额外的羟基。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
