Transition state for alkyl group hydrogenation on Pt(111)

Substituent effects have been used to probe the characteristics of the transition state to hydrogenation of alkyl groups on the Pt(111) surface. Eight different alkyl and fluoroalkyl groups have been formed on the Pt(111) surface by dissociative adsorption of their respective alkyl and fluoroalkyl iodides. Coadsorption of hydrogen and alkyl groups, followed by heating of the surface, results in hydrogenation of the alkyl groups to form alkanes, which then desorb into the gas phase. Temperature-programmed reaction spectroscopy was used to measure the barriers to hydrogenation, ΔEH≠, which are dependent on the size of the alkyl group (polarizability) and the degree of fluorination (field effect). This example is one of only two surface reactions for which the influence of the substituents on ΔE H? has been correlated with both the field and the polarizability substituent constants of the alkyl groups in the form of a linear free energy relationship. Increasing both the field and the polarizability constants of the alkyl groups increases the value of ΔEH ?. The substituent effects are quantified by a field reaction constant of ρF = 27 ± 4 kJ/mol and a polarizability reaction constant of ρα = 19 ± 3 kJ/mol. These suggest that the transition state for hydrogenation is slightly cationic with respect to the alkyl group on the Pt(111) surface, RC + H ←{RC δ+ ...H)?.

Rate constant ratios, kd/kc for the disproportionation/combination reaction have been measured as 0.07 ± 0.02 when an H is removed from the CH2 position of the CF3CH2CHCH3 radical and as 0.

Treatment of methyl chlorodifluoroacetate with aliphatic halides in the presence of equivalent ammount of potassium fluoride, copper iodide and cadmium iodide at 120°C in HMPA for 8 h gave the corresponding trifluoromethyl derivatives in moderate yields.

Addition of Free Radicals to Unsaturated Systems. Part 24. Kinetics and Mechanism of the Gas-phase Thermal Reactions of Trifluoroiodomethane with Propene

The gas-thermal addition of trifluoroiodomethane to propene, at temperatures of 533-583 K, reactant ratios from 1:1 to 4:1, and total pressures of 100-300 mmHg, is shown to be a free-radical chain reaction with the kinetic equation as shown below.It is concluded that initiation is by the reaction of d/dt=k82>0.253I>1.093H6>0.41 iodine atoms, in thermal equilibrium with molecular iodine, with trifluoroiodomethane, and termination is predominantly by reactions involving trifluorobutyl radicals.The Arrhenius parameters found for k8 are discussed in terms of those for the elementary reactions involved on the basis of the proposed mechanism.
