L. Delaude et al., COUPLING AND CARBONYLATION OF IODOAROMATICS AND TERMINAL ALKYNES OR ALKYNOLS CATALYZED BY A DIMERIC PALLADIUM HYDROXIDE, Synthesis, (11), 1994, pp. 1149-1151
The palladium(II) complex [(Ph(3)P)Pd(Ph)mu-OH)](2) is an effective ca
talyst for the coupling and 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.
