Hydration of C≃C bond is a very efficient synthetic step. Currently, there exist ruthenium catalytic complexes, preferably with phosphine or bipyridine ligands, able to hydrate with “anti-Markovnikov” selectivity, producing aldehydes. Although development of novel hydration catalysts was fruitful in recent years, only very few mechanistic studies of mol. structural influences are described. On the model hydration or 1-heptyne, we tested a series of various organophosphine ligands with various nitrogen functionalities having different acid-base properties. This screening showed that ligands with methylene-substituted nitrogen in five-membered ring are very promising to synthesize a catalyst for anti-Markovnikov hydration of alkynes.
