The interaction of Br 2 with Cu(100) was characterized using temperature-programmed desorption (TPD) and low-energy electron diffraction (LEED). Initial exposure to Br 2 resulted in the formation of a c(2 2) LEED pattern and CuBr desorption peaks at 870 and 1000 K. These desorption peaks saturated at a dose of approximately 5 L and were attributed to Br 2 chemisorption....
We report the formation of adsorbed t-butoxy by addition of transient t-butyl radicals to surface oxygen, in the reactions of t-butyl iodide and t-butanethiol on Rh(111)-p(2 1)-O. t-Butanethiol reacts by cleavage of the weak S H bond, forming adsorbed t-butyl thiolate upon adsorption at 100 K. t-Butyl thiolate subsequently forms t-butanol, isobutene and water in the range of 325-345 K via a transient...
