β-Vinylated Tri(1-adamantyl)phosphine: Synthesis, Characterization, and Application in Gold Catalysis.

A β-vinylated tri(1-adamantyl)phosphine was synthesized from tri(1-adamantyl)phosphine through a photocatalytic cycloaddition/base-induced elimination sequence. The electronic and steric properties of the new phosphine were examined through structural characterization of its chalcogenides and gold complex. The gold complex catalyzed hydroamination of alkynes, demonstrating its potential in transition metal catalysis.
