Abstract

original image

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 Ni0 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.
