Hydrotalcite-derived Mg-Al mixed oxides catalyze reactions involving a C-H bond cleavage step, such as aldol-like condensations, alkylations or double-bond isomerizations. We report here the activation of C-H bonds of secondary alcohols using 2-propanol eliminations as a reaction probe.  Our goal was to elucidate the reaction pathways and to ascertain the nature of the surface sites and structures that promote these reactions on Mg-Al mixed oxides of different chemical composition
