Ligand effects in chromium diphosphine catalysed olefin co-trimerisation and diene trimerisation

A series of symmetric and unsymmetric N,N-bis(diarylphosphino)amine ('PNP') ligands (Ar2PN(R)PNAr′2: R = Me, Ar2 = o-anisyl, Ar′2 = Ph, 1, R = Me, Ar2 = o-tolyl, Ar′2 = Ph, 2, R = Me, Ar2 = Ph(o-ethyl), Ar′2 = Ph, 3, R = Me, Ar2 = Ar′2 = o-anisyl, 4, R = iPr, Ar2 = Ar′2 = Ph, 5) and symmetric N,N′-bis(diarylphosphino)dimethylhydrazine ('PNNP') ligands (Ar2PN(Me)N(Me)PAr2: Ar2 = o-tolyl, 6, Ar 2 = o-anisyl, 7) have been synthesised. Catalytic screening for ethene/styrene co-trimerisation and isoprene trimerisation was performed via the in situ complexation to [CrCl3(THF)3] followed by activation with methylaluminoxane (MAO). PNNP catalytic systems showed a significant increase in activity and selectivity over previously reported PNP systems in isoprene trimerisation. Comparing the symmetric and unsymmetric variants in ethene and styrene co-trimerisation resulted in a switch in selectivity, an unsymmetric catalytic (o-anisyl)2PN(Me)PPh 2 (1) ligand system affording unique incorporation of two styrenic monomers into the co-trimer product distribution differing from the familiar two ethene and one styrene ω-substituted alkenes. Complexes of the type [(diphosphine)Cr(CO)4] 8-11 were also synthesised, the single-crystal X-ray diffraction of which are reported. We propose the mechanisms of these catalytic transformations and an insight into the effect of the ligand series on the chromacyclic catalytic intermediates. The Royal Society of Chemistry.

METHOD FOR PRODUCING TRIMETHYLCYCLODODECATRIENE

The invention relates to the production of trimethylcyclododecatriene in a continuous or discontinuous method, by the trimerisation of isoprene in the presence of a catalyst system and a solvent. The raw trimethylcyclododecatriene obtained can be isolated by distillation. The dimethylcyclooctadiene formed as a by-product can also be isolated from the raw product.
