1(2)-(1,1-二烷基-3-丁烯基)-1,3-环戊二烯的合成和~1HNMR谱分析

SYNTHESES AND'HNMR SPECTRA OF 1(2)-(1,1-DIALKYL-3-BUTENYL)-1,3-CYCLOPENTADIENE

6,6-二烷基富烯同烯丙基格氏试剂发生环外双键加成,继而水解,得到一系列1(2)-(1,1-二烷基-3-丁烯基)-1,3-环戊二烯,并对合成的10种新化合物的结构进行了分析。

A series of 1(2)-(1,1-dialkyl-3-butenyl)-1,3-cyclopentadieneshas been synthesized by exocyclic addition reactions of 6,6-dialkylfulveneswith allyl Grignard reagent followed by hydrolysis.These new compoundshave not been reported in literatures.The structures of these compoundshave been characterized by ~1HNMR spectra.
