Upper Rim-Bridged Calix[4]arenes via Cyclization of <i>meta</i> Alkynyl Intermediates with Diphenyl Diselenide

A Sonogashira coupling of <i>meta</i>-iodocalix[4]arene with various terminal acetylenes confirmed that the <i>meta</i> position of calixarene is well addressable, and that both thermal and microwave protocols led to good yields of alkynylcalixarenes. Alkynes thus obtained we...
