Under photochemical irradiation, the hydration of aryl alkynes in the presence of water proceeds in good yields to afford the corresponding ketone, using a water-soluble rhodium (I) catalyst. The catalyst is effective for internal and terminal alkynes and showed high functional group compatibility. A low catalyst loading, low temperature and shorter duration of photolysis are ideal feature of reaction. The catalyst can be reused several times under aerobic and aqueous conditions, exemplifying the robust nature of the catalyst. In comparison with known Rh and other metal catalysts, the present reaction provides a remarkable green approach for alkyne hydration reactions.

在光化学辐射下，使用水溶性铑（I）催化剂，在水存在下芳基炔烃的水合反应以良好的产率进行，从而得到相应的酮。该催化剂对内部和末端炔烃有效，并显示出高官能团相容性。低催化剂负载量，低温和较短的光解持续时间是反应的理想特征。该催化剂可以在有氧和含水条件下重复使用几次，体现了该催化剂的坚固特性。与已知的Rh和其他金属催化剂相比，本反应为炔烃水合反应提供了显着的绿色方法。
