δ-Hydrogen Abstraction from Alkyl and Phosphine Ligands Co-ordinated to Platinum(II); Formation of Benzoplatinacyclopentene Complexes

Reactions of (cod = cyclo-octa-1,5-diene) with Mg(CH2C6H4Me-o)Br and tertiary phosphines (PR3) afford cis- (R = Et or Ph), which on refluxing in xylene give the benzoplatinacyclopentene complexes via δ-hydrogen abstraction reactions.Using PPh2(C6H4Me-o), metallation of the phosphine is preferred and the first obtained product after refluxing in xylene is >.On further refluxing in xylene, this compound again eliminates o-xylene to give the known .Using P(C6H4Me-o)3, the bulkiness of the phosphine makes alkylation unfavourable and the fluxional Br> is obtained.The variable-temperature n.m.r. spectra of this compound are interpreted in terms of hindered rotation around the Pt-P and P-C bonds giving rise to two different conformers at low temperature, each with all methyl groups non-equivalent.The compounds have been identified by their spectroscopic properties and some of their reaction chemistry is discussed.
