Abstract
Nickel diphenylphosphinoenolate complexes are prepared from ortho-HX-substituted phenacylidenetriphenylphosphoranes (X = O, NMe, NPh) which display strong intramolecular hydrogen bonding between the enolate oxygen and the H–X function; this feature dramatically influences the molecular mass distribution of the oligomers obtained by catalytic oligomerisation of ethene.Keywords
