The cyclodimerisation reaction of butadiene leading to methylene-2 vinylcyclopentane catalysed by zerovalentnickel in presence of Threophos ligand has been optimised using the experimental research methodology.Thus, we obtain the cyclodimer with 70percent of selectivity for a conversion rate of 90percent and this in the following conditions: temperature 80 deg C; time 6 hours; /0>=1; /0>=80; /0>=50.
Threophos: A New Chiral Aminophosphine Phosphinite (AMPP) Ligand Highly Efficient in Asymmetric Hydrovinylation of Cyclohexa-1,3-diene Catalyzed by Nickel Complexes

Threophos is a potential tridentate ligand obtained from threonine. (S)-(+)-3-Vinylcyclohex-1-ene is produced quantitatively in 93percent ee from asymmetric hydrovinylation of cyclohexa-1,3-diene catalyzed by the Ni(COD)2-AlEt2Cl- syste
