Abstract
Unstable CpNi(vinyl) compounds of the type CpNi-CR'= CR(2) (R' = CH3, C6H5, R = CH3) are formed in the reaction of nickelocene with vinyllit hium or -magnesium compounds. CpNi(vinyl) reacts further to form pi-al lyl complexes and other compounds not yet fully characterized. For R' = CH3, pi-allyl complex 1 is formed and for R' = C6H5 two pi-allyl iso mers anti-2a and syn-2b are formed. The mechanisms of alpha-, beta-, g amma- and eta-H elimination and of hydrogen transfer reactions are dis cussed.
