Reactions of potassium carbonyl(π-cyclopentadienyl)nickelate with butenyl and cyclopropylmethyl halides

Abstract

The reaction of carbonyl(π-cyclopentadienyl)nickel anion with but-3-enyl and cyclopropylmethyl halides has been investigated. In the former case, the only isolated product is 1–3-η-but-2-enyl-π-cyclopentadienylnickel (85 : 15 (trans : cis) whereas in the latter, a cyclopropylmethylnickel complex could be isolated. This was converted by thermolysis, or more effectively by photolysis into a 1-σ : 4–5-η-1-oxopent-4-enylnickel, most probably derived by insertion of a cyclopropane C–C bond into the metal carbonyl system.
