【従来の技術】
(チオフェン/フェニレン)コオリゴマー類の製造方法としては、例えば、4−ブロモビフェニルと2−ヨードチオフェンのグリニヤール試薬とを二価のニッケル錯体の存在下で反応させて2−(4−ビフェニリル)チオフェンとなし、次いで、2−(4−ビフェニリル)チオフェンの5位をブロモ化した後に、2−チオフェンボロン酸を塩基とパラジウム触媒の存在下で反応させることにより、5−(4−ビフェニリル)−2,2’−ビチオフェンを製造する方法等が知られている(特開2000−26451号公報)。しかしながら、この方法では、1段階目の反応にニッケル錯体を使用しているが、ニッケルは近年その発ガン性が問題となっており、工業的に有利な方法とは言い難い。また、最終生成物である5−(4−ビフェニリル)−2,2’−ビチオフェンの4−ブロモビフェニルに対する収率は、5.2%と低く、工業的に有利な方法とは言い難い。

[Prior art]
As a method for producing (thiophene / phenylene) cooligomers, for example, 4-bromobiphenyl and a Grignard reagent of 2-iodothiophene are reacted in the presence of a divalent nickel complex to produce 2- (4-biphenylyl) thiophene. And then brominating the 5-position of 2- (4-biphenylyl) thiophene, and then reacting 2-thiophenboronic acid with a base in the presence of a palladium catalyst to give 5- (4-biphenylyl) -2.
