A palladium-catalyzed 4-fold domino reaction consisting of two carbopalladation reactions and two C-H activation reactions, followed by the introduction of an acrylate moiety, led to the tetra-substituted helical alkene A2, using the dialkyne A3 as a substrate. The alkene was copolymerized with butyl acrylate by using the reversible addition-fragmentation chain transfer polymerization (RAFT) to give the desired polymeric switch A1.
钯催化的 4 步串联反应,包括两个碳钯化反应和两个 C-H 活化反应,接着引入丙烯酸盐部分,使用二炔 A3 作为底物,得到四取代的螺旋烯烃 A2。该烯烃通过可逆加成-断裂链转移聚合(RAFT)与丙烯酸丁酯共聚,得到所需的聚合物开关 A1。
