formed as an intermediate in the reaction of nickelocene with vinyllithium, in the presence of ethylene reacts in part via reductive coupling of two vinyl groups to give the binuclear (CpNi)2(η4-butadiene) and in part via ethylene insertion into the vinylnickel bond to give the η1,η2-3-butenyl complex, which isomerizes at elevated temperatures to the η3-1-methylallyl compound.
CPNI乙烯基,其经由两个乙烯基的还原偶联形成为与乙烯基锂二茂镍的反应中的中间体,在乙烯发生反应的存在部分,得到的双核(CPNI)2(η 4 -丁二烯),并部分地通过乙烯插入vinylnickel键,得到η 1,η 2 -3-丁烯基复合物,其在升高的温度异构化成η 3 -1甲基烯丙基化合物。
