The cotrimerisation of 3,3-dimethylcyclopropene (1) with methyl acrylate is catalyzed by phosphane- or phosphite-Ni(0) compounds under mild conditions (40 - 50 deg C).Depending on the nature of the phosphane or phosphite 1 and methyl acrylate cotrimerise mainly in the ratio 2 : 1 or 1 : 2 to give cis/trans-5 or cis/trans-6 and cyclic cis/trans-7. trans-5 and trans-6 are thermally more labile than the corresponding cis compounds.Heating to 200 deg C for two hours induces their complete rearrangement to 12 and 13 or 14 via 1,5-homodienylhydrogen shift.
