“…A six-particle classical trajectory study basically agrees with the above conclusions, and yields additional information:72-75 (6) Substitution involves strong interactions between at least 4 atoms. (7) No inertial isotope effects were found when CH4 was replaced by CD4.…”

“…However, this yield was mainly due to the reactions of thermal ^Br atoms with impurities and radicals, as the addition of 0.5 mol % Br2 reduced this yield to 1%. Organic yields for scavenged "When CF^Br was used as the precursor, the OY is 3%.283 6 When H^Br and H82mBr were used as the precursors, the OY are 4.5 and 5.1%, respectively.…”

“…BRINKMAN has just published a review on the reactions of recoil atoms with haloethylenes [1 ]. Of the studies made with chloroethylenes more attention seems to have been paid to eis-and trans-dichloroethylenes to obtain information by invest^ating the retention and racemisation of both geometric configurations [2][3][4][5][6][7][8].…”

AbstiactReactions of recoil "Q in mixtures of CaHa, and CjHaj and C^Q« with hydrocarbons, alcohols, amines and anisole are studied. The yields are enhanced in mixtures upto about 10 mol % of the additive. Direct hot replacement and addition-elimination reactions in an excited solvent cage seem to account the yields in C,a,. The model developed by Urch has been used to calculate the reactivity Parameters. The organic yields in mixtures of CjQ, with hydrocarbons and alcohols arise mainly from hot-zone reactions while the same conclusion could not be drawn in case of CjHQj mixtures. ExperimentalTrichloroethylene (E-Merck) and tetrachloroethylene (BDH) of reagent grade were distilled and used. Samples of the mixtures in soft glass vials were irradiated by neutrons from ^"Cf and '"Sb/Be sources for 30 and60min respectively. FoUowing irradiation, organic and aqueous layers were separated as described [21 a], ^'Cl activity was counted on a Nal(Tl) scintillation coimter.
