  Regioselective Reductive Hydration of Alkynes To Form Branched or Linear Alcohols

  摘要：

  The regioselective reductive hydration of terminal alkynes using two complementary dual catalytic systems is described. Branched or linear alcohols are obtained in 75-96% yield with >= 25:1 regioselectivity from the same starting materials. The method is compatible with terminal, di-, and trisubstituted alkenes. This reductive hydration constitutes a strategic surrogate to alkene oxyfunctionalization and may be of utility in multistep settings.

  Anti‐Markovnikov alkyne hydration 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 ambient temperature.

These studies also show that this substituent increases hydrogenation activity by promoting activation of the reductant.
