The Preparation of a New Kind of Carbosilane Dendrimer with 4-(Naphthalen-1-yl)phenyl Core-An Application of Suzuki Coupling Reaction

摘要

Using the divergent method,carbosilane dendrimers with p-bromophenyl core were synthesized by using alternating Grignard and hydrosilylation reactions.And then,alpha-naphthalenyl was connected to the core by using Suzuki coupling reaction.This gave a new carbosilane dendrimer with a 4-(naphthalen-1-yl)phenyl core.All the products were characterized by IR,~1H NMR,~(13)C NMR,~(29)Si NMR,and MS.The study shows that Suzuki Coupling reaction is an effective and powerful core-functionalization method and a satisfactory result can be achieved through prolonging the reaction time.
