摘要

Abstract Hexafluorobenzene reacts with Et 3 SiC CLi to give p-Et 3 SiC CC 6 F 4 C CSi- Et 3 and pentafluorophenylcopper couples with BrC CSiEt 3 to give C 6 F 5 C CSiEt 3 in good yield. Treatment of the products with aqueous methanolic alkali gives p-HC CC 6 F 4 C CH and C 6 F 5 C CH respectively.
