Ni takes a load off : Nickel(0) and a strained alkene react to form a stable tris(alkene) complex, which eliminates the corresponding trans , trans , trans ‐cyclobutane upon heating. A higher proportion of alkene to Ni 0 precursor yielded the first all‐alkyl complex of nickel(IV) (see structure; Ni: green). These reactions, which involve ligand coupling, are driven by relief of ring strain in the alkene.
