Palladium-Catalyzed Multialkynyl Cross-Coupling Reactions with Tetraalkynylindates

초록

An efficient Pd-catalyzed multialkynyl cross-coupling reaction performed with tetraalkynylindates generated in situ from the reaction of 1 equiv. of indium trichloride with 4 equiv. of organometallic reagents has been developed to produce symmetric as well as unsymmetric multialkynyl-substituted aromatic compounds in good-to-excellent yields. In these reactions, the four acetylide groups in the tetraalkynylindates transferred effectively to a variety of aryl bromides.
