Generations 1 to 3 of dendrimers ended by water-soluble phosphines are synthesized and their ruthenium complexes used as catalysts in aqueous media; a slightly positive dendritic effect on the regioselectivity is observed for hydration alkynes large biphasic (water/heptane) catalysed isomerisation allylic alcohols ketones where products easily isolated catalyst can be reused several times, even first generation.
