Secondary phosphine oxides stabilized Au/Pd nanoalloys: metal components-controlled regioselective hydrogenation toward phosphinyl (Z)-[3]dendralenes

Abstract

A series of gold/palladium nanoalloys stabilized by secondary phosphine oxides have been prepared for the first time. The nanocatalysts exhibit excellent regio- and chemo-selectivity in the hydrogenation of conjugated enynes, providing a mild and highly efficient way to access phosphinyl (Z) and (Z,Z)-[3]dendralenes.
