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.
