## Abstract magnified image A convenient ironβcatalyzed crossβcoupling reaction of terminal alkynes with vinyl iodides is reported. The reaction was applicable to various acetylenes and vinyl iodides. The present reaction provides an efficient, environmentally friendly protocol to afford conjugate
## Abstract A copperβcatalyzed crossβcoupling 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 1.0β2.5 molβ% of Cu~2~O and 1.0β2.5 molβ% of xantphos as the catalyst.
