Abstract

With the help of the photothermal effect of gold nanoparticles (AuNPs), the hydration of the arylacetylenes to synthesize carbonyl compounds is successfully achieved. The reaction proceeds smoothly for various substrates and the ketone products are obtained in good isolated yields up to 91%. The successful gram-scale and sunlight-exposure experiments illustrate the potential application of this method in the future organic syntheses.
