✦ Synopsis

A palladium-catalyzed cross-coupling reaction of aryl trimethoxysilanes with terminal alkynes was described. Thus, di-substituted alkynes were prepared in moderate to good yields. The electron-deficient terminal alkynes also worked well in the procedure.

## Abstract A copper‐catalyzed cross‐coupling reaction of alkynes with aryl iodides is described. The system tolerates a broad range of functional groups and enables the use of sterically demanding substrates with only 1.0–2.5 mol‐% of Cu~2~O and 1.0–2.5 mol‐% of xantphos as the catalyst.

Coupling reaction of aryl and vinyl halides with terminal alkynes using a catalyst system of copper(I) iodide -triphenylphosphine proceeds efficiently in the presence of potassium carbonate to give the corresponding unsymmetrical acetylenes in good yield.
