General description

Mechanism of the fluoride-free, palladium-catalyzed cross-coupling reaction of 2-iodothiophene with potassium (E)-heptenyldimethylsilanolate has been investigated. 2-Iodothiophene participates in microwave-enhanced, rapid homogeneous-phase version of the Sonogashira reaction.

Application

2-Iodothiophene was used in the synthesis of (E)-and (Z)-2,3-difluoro-3-aryl substituted acrylic esters. It was also used as monomer in the preparation of thin conductive films via plasma polymerization of 2-iodothiophene.
