Coupling and carbonylation of iodoaromatics and terminal alkynes or alkynols catalyzed by a dimeric palladium hydroxide

Article abstract of DOI:10.1055/s-1994-25660

The palladium(II) complex [(Ph₃P)Pd(Ph)(μ-OH)]₂ is an effective catalyst for the coupling aud carbonylation of alkynes and iodoarenes to give acetylenic ketones in 63-94% yields. Acetylenic hydroxy ketones were formed using secondary or tertiary alkynols as reactants.
