Anti‐Markovnikov alkynehydration provides a valuable route to aldehydes. Half‐sandwich ruthenium complexes ligated by 5,5′‐bis(trifluoromethyl)‐2,2′‐bipyridine are remarkably active for this transformation. In the presence of 2 mol % metal, a wide range of functionalized aliphatic and aromatic alkynes are hydrated in high yield at ambienttemperature.

Unconjugated alkynyl ketones and aldehydes are selectively hydroborated to give the corresponding olefinic carbonyl compounds after protonation, or dicarbonyl compounds after oxidation. (C) 1997 Elsevier Science Ltd.
