Treatment of bis(1,5-cyclooctadiene)platinum with 1,3-bis(di-t-butylphosphino)propane and various styrenes and subsequent protonation of the resultant platinum(0) alkene complexes affords a series of cationic complexes t2P(CH2)3PBut2)(η3-anti-1-MeCH6H4X)>(BF4) (X = Br-3, Br-4 (2b), H, Me-4, MeO-4).These have been characterized by NMR spectroscopy and, in the case of 2b, by a single-crystal X-ray diffraction study.

Reaction of the platinum(0) styrene complexes 2-CH2=CHC6H4X)> 1a-1f (X = Br-3, Br-4, Me-4, F-4, F-3 or MeO-4) with HBF4 in diethyl ether afforded the η3-methylbenzyl complexes 3-MeCHC6H4X)> 2a-2f.The effect of phenyl substitution on the asymmetry of the η3-methylbenzyl interaction was measured by 31P- NMR spectroscopy and it was found that, in general, the more electron releasing the substituent, X, the more asymmetric is the bonding.Complexes 2a-2f lose styrene reversibly to form the hydride-bridged dinuclear platinum complex 2>2.Displacement of styrenes from 2a-2f by ethene and bicyclohept-2-ene affords known complexes stabilized by a three-centre, two-electron (agostic) bond.
