We have taken steps to develop a methodology for quantifying the kinetics and dynamics of bimolecular reactions through spectroscopic monitoring of reactants and products during exposure of well-ordered self-assembled monolayers (SAMs) to supersonic beams of atomic reagents. The use of a SAM stabilizes highly energetic intermediates formed from bimolecular reactions at the vacuum/film interface...

α-Diazo arylketones are well-known substrates for Wolff rearrangement to phenylacetic acids through a ketene intermediate by either thermal or photochemical activation. Likewise, α-substituted p-hydroxyphenacyl (pHP) esters are substrates for photo-Favorskii rearrangements to phenylacetic acids by a different pathway that purportedly involves a cyclopropanone intermediate. In this paper, we sho...

Ketene, a versatile reagent in production of fine and specialty chemicals, is produced from acetic acid. We investigate the synthesis ketene acid over (3,0;1,1) surface Cu2O(1 0 0) through analysis adsorption desorption characteristics formic acids. The results allow us to establish reaction mechanism for formation. Observations x-ray photoelectron spectroscopy (XPS), scanning tunneling microsc...
