Abstract [en]

Alkyl aryl tellurides and a tellurol ester were used as coupling partners in Pd(0)-catalyzed Sonogashira reactions. Microwave-assisted reactions of alkyl aryl tellurides with alkynes in the presence of Cut and catalytic amounts of Pd(PPh(3))(4) produced alkynyl arenes. Similarly, a tellurol ester on reaction with alkynes afforded alkynyl phenyl ketones in the presence of Cut and a catalytic amount of Pd(PPh(3))(4) at room temperature.
