【摘要】 以甲基三氯硅烷、烯丙基氯化镁为原料,采用格氏法合成了端烯丙基的碳硅烷树枝状化合物;再与甲基氢二氯硅烷进行硅氢加成反应,合成出末端为Si—Cl键的树枝状化合物;然后以四氢呋喃为溶剂,与溴苯格氏试剂反应,得到端苯基的碳硅烷树枝状化合物。并用红外光谱和核磁共振谱进行了表征。结果表明,采用发散式合成法制备端苯基的碳硅烷树枝状化合物,反应过程易控制,总产率为91%。更多还原

【Abstract】 Firstly, allyl-terminated carbosilane dendermers was synthesized by grignard reaction with chlorotrimethylsilane and chloropropene materials. Secondly, it had hydrosilation reaction with methyl dichloro silane; thirdly, phenyl-terminated carbosilane dendermers was synthesized supplying with allyl-terminated carbosilane dendermers with THF. All the dendrimers were characterized by IR and 1H NMR spectroscopy. The result showed that the preparation of phenyl-terminated carbosilane dendermers could be controlled easily with the yield of 91%.更多还原
