Abstract
Abstract A palladium catalyst that mediates the one-pot sequential Sonogashira and decarboxylative coupling of propiolic acid with two different aryl bromides has been developed. Selective coupling of the first aryl bromide was achieved in the presence of a copper-free, monometallic catalyst generated in situ from allylpalladium chloride dimer and SPhos with tetra-n-butylammonium fluoride as the base in an N-methyl-2-pyrrolidone/ ...
