Thiolate-protected Gold Nanoclusters Au-25(phenylethanethiol)(18): An Efficient Catalyst for the Synthesis of Propargylamines from Aldehydes, Amines, and Alkynes
In this study, we report a thiolate-protected Au nanocluster, Au-25(phenylethanethiol)(18) [Au-25(PET)(18)], which serves as an efficient catalyst by a three-component coupling reaction (A(3) reaction) of aldehydes, amines, and alkynes to give the corresponding propargylamines in good to excellent yields.
