Abstract
In benzene, neither sec-butyllithium (1) nor 3-methoxypropyllithium (2 ) react with ethylene, while in solutions containing 1 plus 2 3-methyl pentyllithium (3) is produced by ethylenation of 1. Clusters 1(n)2(4.n )(n:0 - 4) are indicated by NMR and 1(2)2(2) is deduced to be the most reactive species. At [2]:[1] = 2, the reaction order in 1 is 0.74, si gnifying reversible formation of a pre-reaction complex 1(2)2(2).ethyl ene.
