In this presentation we will survey some of the recent advances in our research on the understanding of the factors that affect selectivity in the hydrogenation of organic molecules promoted by platinum catalysts.  In the first of three themes, we elaborate on the progress made in our laboratory in our study of the role that carbonaceous surface deposits play in the hydrogenation of olefins and on the kinetics of hydrogen adsorption-desorption and diffusion under catalytic conditions.  We will then briefly expand on the implications of our conclusions to more complex systems, with emphasis on the selective hydrogenation of unsaturated aldehydes.  The last section will be dedicated to the discussion of enantioselective hydrogenation processes using chiral modifiers.
