Catalytic Hydration of Alkynes and Its Application in Synthesis

  title={Catalytic Hydration of Alkynes and Its Application in Synthesis},
  author={Lukas Hintermann and Aur{\'e}lie Labonne},
The catalytic addition of water to alkynes (hydration) generates valuable carbonyl compounds from unsaturated hydrocarbon precursors. Traditional mercury(II) catalysts hydrate terminal alkynes with Markovnikov selectivity to methyl ketones. Much research has been devoted to finding catalysts based on less toxic metals, the most promising being gold(I), gold(III), platinum(II), and palladium(II). Catalytic anti-Markovnikov hydration of terminal alkynes to aldehydes has been realized in an…

Hydration of terminal alkynes catalyzed by water-soluble cobalt porphyrin complexes.
Water-soluble cobalt(III) porphyrin complexes were found to promote the hydration of terminal alkynes to give methyl ketones and can be performed on a gram scale, and the catalyst can be recovered by aqueous workup.
Bismuth(III)-Catalyzed Hydration of Terminal Alkynes: Sustainable Synthesis of Methyl Ketones in Batch and Flow
Environmentally benign synthesis of methyl ketones is demonstrated via unprecedented bismuth(III)-catalyzed activation and Markovnikov-type hydration of terminal acetylenes. Besides a batch process
Experimental and Theoretical Study of Gold(III)-Catalyzed Hydration of Alkynes
The properties of different Au(III) halo dithiocarbamate complexes of structure [AuX2(S2CN(R)2)] as suitable catalysts for the hydration reaction of phenylacetylene have been tested. Moderate

Regioselectivity in the Au-catalyzed hydration and hydroalkoxylation of alkynes.
This article aims to draw attention to the general problem of regioselectivity in homogenous gold catalysis and a select set of examples is presented to highlight the challenges and survey some of the strategies employed to address this problem.
Bismuth salts in catalytic alkylation reactions.
Recent advances in Bi(III)-catalyzed alkylations of arenes, 2,4-pentanediones and various oxygen- and nitrogen-containing nucleophiles are shown.
