Abstract

Palladium-catalyzed carbonylative cross-coupling reaction of ethynylstibane (Ph⌯ SbPh 2) and aryl iodides (Ar-I) is described. The reaction of the stibanes and the halides under 1 atm of carbon monoxide in N, N-dimethylacetamide using a combination of 5 mol% Pd (OAc) 2 and 4 equivalents (20 mol%) of PPh 3 brought about carbonylative cross-coupling reaction to afford arylethynylketones [ArC (O)⌯ Ph] in good yields along with a small amount of ...
