A convenient synthesis of some acetylene-tethered chiral and achiral dialdehydes using Sonagashira-Hagihara coupling has been accomplished. Dibromobenzenes and enantiopure dibromobinaphthol were functionalized to provide the acetylene-tethered dialdehydes in moderate to good yields.

Keywords: Acetylene, dialdehydes, Sonagashira-Hagihara coupling, binaphthyl.
