Abstract
<p indent="0mm">Aryl fluorosulfates were employed as coupling partners with terminal alkyne or propiolic acid in Sonogashira reaction. The symmetrical diarylalkynes were synthesized <italic>via</italic> decarboxylative cross-coupling of aryl fluorosulfates and propiolic acid in good yields. The unsymmetrical arylalkynes were obtained from aryl fluorosulfates and terminal alkynes or decarboxylative cross-coupling of aryl iodides, aryl fluorosulfates and propiolic acid in one pot with moderate to good yield.
