The secondary structure of a bifunctional catalyst positions a crucial reactive proton in the final intermediate of anti-Markovnikovalkynehydration to give an aldehyde. NMR coupling and isotopic labeling studies elucidate the location of this proton and its involvement in hydrogen bonding.

phosphorylated derivatives of all their prototropic forms (α-amino ketones, α-hydroxy imines, and β-hydroxy enamines) were obtained for the first time. The relative thermodynamic stability sequence of α-amino ketones was found to be reversed upon their phosphorylation: O-substituted forms were more stable than N-substituted ones, in contrast to the equilibrium between the prototropic isomers.
