产品介绍：

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 yield1-Ethynyl-4-fluorobenzene may be used in the synthesis of the following: · 3-(4-Fluorophenyl)-1H-isochromen-1-one by reacting with 2-iodobenzoic acid in the presence of copper catalyst. · 4-Bromo-3,5-difluoro-2,6-bis-(4-fluoro-phenylethynyl)-pyridine by reacting with 2,4,6-tribromo-3,5-difluoropyridine by palladium catalyzed Sonogashira reaction. · 1-(4-Fluorophenyl)-3-methoxy-3-(4-methoxyphenyl)propan-1-one by reacting with p-anisaldehyde. · 5-(4-Fluorophenyl)-1-(2-nitrobenzyl)-1H-1,2,3-triazole by reacting with 1-(bromomethyl)-2-nitrobenzene in the presence of sodium azide. 1-Ethynyl-4-fluorobenzene, a substituted phenylacetylene, may be used in the synthesis of aryl acetylenes, via Sonogashira type cross coupling reaction with various haloarenes in the presence of bis(μ-iodo)bis((-)-sparteine)dicopper(I) catalyst
