VCH = 4-vinylcyclohexene: COD= cis-1. 5-cyclooctadiene: DVCB = cis-l. 2-divinylcyclobutane.When L = P(OC 6 H 4 PH "), at 60C. COD= 94.5%: L =PPhEt 1 • COD= 38.2%: DVCB = 12.6%: VCH = 46.0% of total products.cis-Divinylcyclobutane is also formed with basic phosphines at low temperatures( ~ 60 "C). At higher temperature a nickel catalysed Cope rearrangement to 1. 5-COD occurs.Whereas nickel complexes catalyse the trimerization or dimerization ofbutadiene to cyclic products, palladium catalysts produce linear oligomers. Whenbis(dibenzoylacetone)palladium is treated with butadiene at low temperature, ayellow air sensitive complex ( IJ 1 , 1J '-dodecatrienediyl)palladium is formed initially.It decomposes above -20 C in the absence of butadiene and in its presenceactively catalyses its trimerization to linear 1. 3. 6. 1 0-dodecatetraene. In contrastto the corresponding nickel intermediate. the substituents on the allylgroups are syn. Treatment with a diphosphine affords a metallacycle whichcontains a huge 13-membered ring. If (A) or (B) is allowed to warm above -20 Cor is treated with ligands (Ph ,P or CO). dodecatetraene isomers are released(Fig. 12.7).In the presence of added ligand (Pd:L = 1: l ). l, 3, 7-octatriene isomers areobtained (Fig. 12.8). The conformation ofthe Cs chain in the intermediate (C) basbeen determined in solution by n.m.r. spectroscopy and also in the solid state(L = Me 3 P) by X-ray diffraction.
