General Description

1-Ethynyl-4-fluorobenzene (pFAB) is a fluorobenzene derivative. Trianionic pincer alkylidyne complex catalyzed polymerization of 1-ethynyl-4-fluorobenzene has been reported. The surface of the iodophenyl-terminated organic monolayers has been modified by Sonogashira coupling of the iodophenyl groups found on the surface with pFAB. Dimerization catalyzed by Y[N(TMS)₂]₃ and 4-chloroaniline gave exclusive formation of one of three possible enediynes in excellent yield.
