Esters which are unstable and/or too reactive, such as those of CF3S03H, require a negative modifier (donor), e.g., a dialkyl sulphide, to give living systems such modifiers form a D-A complex with an acceptor centre, e.g., the acidic protons, at the growing end. [Pg.721]

The reactions of [WF6] with binary fluorides may be explained by the disproportionation of this ion to WF6 and WF4 followed, in some instances, by the complex-ing of the WF4 with the fluoroanion.431" WC16 or WC15 react with an excess of a dialkyl sulphide, R2S (R = Me or Et), via an S-dealkylation sequence to produce (R3S)2[WC16] 4316 Synthetic procedures suitable for the preparation of WOX2 (X = Cl or Br) have been described432 and thermochemical data have been obtained for WSF2.352... [Pg.130]

R2S represents a series of symmetrical dialkyl sulphides of increasing complexity. As expected, the rate constants decrease with increasing chain length and branching of the alkyl substituents. The effects on the activation parameters are rather small, but it is obvious that the activation enthalpies for the branched substituents are larger than for the linear ones, and that there is a decrease of the negative activation entropies with increasing complexity within each series (linear and branched, respectively). ... [Pg.142]

CB-D and PD antioxidants thus have compiementary functions and when used together they act synergistically, producing an effect greater than that of the sum of their individuai effects. Many sulphur compounds (e.g. thiols, their metal complexes and dialkyl sulphides) are known to destroy hydroperoxides cataiyticaiiy [17,18], whereas simple phosphite esters are stoichiometric hydroperoxide decomposers [11]. [Pg.226]

Kinetic parameters for the reaction of [Pt(bipy)Cl2] with diethyl sulphide were obtained in the work described in the previous paragraph, as necessary information for the comparisons with bidentate N- and S-bonding ligands. Rate constants and activation parameters for the reactions of [Pt(dien)X]+, where X = Cl, Br, or I, with dialkyl sulphides have also been determined. These results may be compared with known kinetic parameters for reactions of uncharged platinum(n) complexes with thioethers. The reactions of... [Pg.150]

Charge-transfer oxidations of a series of dialkyl and mixed alkylaryl sulphides leads to high yields of sulphoxides by the same photochemical procedure. Intermediates formed in the charge-transfer activation of the thioether complexes were probed by time-resolved spectroscopy. The spectra transient with =500 nm in tetrahydrothiophene were attributed to the corresponding radical cations ... [Pg.205]
