A binding pocket for water is created in 1 by the imidazolyl phosphane ligands and the RuII center. Compound 1 proves to be an excellent catalyst for a highly selective anti‐Markovnikov hydration of terminal alkynes to give aldehydes rather than isomeric ketones under near‐neutral conditions (aldehyde‐to‐ketone ratio up to 1000:1).
