Abstract
A series of [M(R2PC2H4PR2)(butadiene)] complexes of Ni, Pd and Pt has been prepared and their structures investigated NMR-spectroscopically. The nickel and palladium complexes, irrespective of the substituents at phosphorus, contain a fluxional η2-bonded butadiene molecule. In the case of platinum the bonding mode is ligand dependent: an η2-arrangement is observed where R is tert-butyl or cyclohexyl while when R is isopropyl the butadiene adopts an η1, η1-arrangement to give a platinacyclopentene derivative.Keywords
