Dechlorination of fluorinated 1,1-dichloroethanes on Pd(111)
Article Abstract:
A study was conducted on the atmospheric chemistry of stratospheric ozone depletion and the replacement of chlorofluorocarbons (CFCs) with environmentally benign materials containing similar properties. The experiment used fluorine substitution to probe the nature of the transition state for the elementary step of C-Cl bond cleavage in CFCs on a Pd(111) surface. Results of the study are discussed.

Transition state for [beta]-hydride elimination in alkyl groups on Pt(111)
Article Abstract:
The transition state for [beta]-hydride elimination on Pt(111) surface was investigated by studying the effects of fluorine substitution on the barriers to [beta]-hydride elimination, [Delta][E.sup.plus.sub.[beta]H]. The transition state for [beta]-hydride elimination is less polarized on the Pt(111) surface with respect to the initial state alkyl group than on the Cu(111) surface.

The transition state for carboxylic acid deprotonation on Cu(100)
Article Abstract:
The kinetics of acid deprotonation on the Cu(100) surface are studied using four different fluorinated carboxylic acids. All four acids adsorb molecularly on Cu(100) at 90 K but deprotonate during heating to form carboxylates on the surface at temperatures below 300 K.
