A new method for the synthesis of stereodefined organogold(I) compounds has been developed using an alkyne hydrozirconation and Zr to Au transmetalation sequence to prepare a series of functionally diverse (E)-alkenylgold(I) compounds that were inaccessible or unreported using other synthetic methods. This facile reaction sequence is complete in 4 h at ambient temperature and can employ commercially

Three-component coupling of bis(dialkylamino)chloroborane, alkynes and organozirconium reagents proceeded in the presence of palladium catalysts, leading to the formation of stereo-defined alkenylborane derivatives via cis-carboboration of carbon–carbon triple bonds.
