Abstract
A microwave-enhanced, rapid and efficient homogeneous-phase version of the Sonogashira reaction is presented. It has been applied to the coupling of a ryl iodides, bromides, triflates, and aryl chloride, as well as pyridine an d thiophene derivatives with trimethylsilylacetylene. Excellent yields (80- 95%) for substrates containing a large variety of substituents in different positions are obtained in 5-25 min.
