An air-stable half-sandwich ruthenium complex is a highly active catalyst for the anti-Markovnikov reductive hydration of alkynes, involving the decarboxylation of formic acid, hydration of the alkyne, and hydrogenation of the intermediate aldehyde. A wide array of terminal alkynes are efficiently processed to linear alcohols using as little as 2 mol % of catalyst at ambient temperature.
