Activation Volumes for Intramolecular Oxidative C-X (X = H, F, Cl or Br) Addition to Platinum(II) Imine Complexes as a Proof of the Intimate Mechanism

The kinetics of C-X (X=H, F, Cl or Br) bond activation of ring-substituted, PhCHNCH2Ph, type imines via intramolecular oxidative addition to platinum(II) complexes has been studied in acetone and toluene solution at different temperatures and pressures.Although the activation parameters determined are within the range expected, the latter is extremely large (ΔH from 25 to 70 kJ mol-1, ΔS from -220 to -45 J K-1 mol-1, ΔV from -3.12 to -9.5 cm3 mol-1).No differences were found for the reactions carried out in acetone or toluene, indicating that no planar transition state is formed during the reaction and that a common highly ordered three-centered C-Pt-X intraction is present for all the imines used.A good correlation was also obtained for the ΔS and ΔV values, independently of the solvent used, confirming the non-polarity of the transition state.A deviation from this pattern is observed only for fluorinated imines both in acetone and toluene solutions; this result is interpreted by considering an earlier transition state for the oxidative addition of C-F that has not yet produced an important volume contraction of the platinum centre despite the important spacial organization of the ligand, as shown by the very negative values of ΔS.

Synthesis and Chemical Behavior of Perchlorophenylacetylene

Perchlorophenylacetylene (6) is synthesized in three steps: (1) vicinal reductive dechlorination of perchlorostyrene (1) to (pentachlorophenyl)acetylene (2), (2) conversion of 2 into its silver acetylide (7), and (3) chlorination of 7 to 6.Some thermal an

Polyhalobenzylic disulfooxonium compounds

Polyhalobenzylic disulfooxonium compounds are produced by the reaction of aromatic methyl, halomethyl or hydroxymethyl substituents with sulfur trioxide. The disulfooxonium salts are readily converted to alcohols by hydrolysis to provide monomers for the production of fire resistant polymers and additives for polymers. Likewise, the disulfooxonium compounds of this invention present chemical intermediates for a wide range of useful products such as halogenated pesticides.
