Lithiation of (Z)-2-lithiostyrene with t-butyllithium/TMEDA pentane led directly to (Z)-2-lithio-ortho-styryllithium. Subsequent treatment of this dilithio compound with difunctional electrophiles allowed the preparation of a variety of benzo[b]heteroles.
用叔丁基锂/ TMEDA戊烷锂化(Z)-2-锂硫基苯乙烯直接导致(Z)-2-锂硫基邻苯乙烯基锂。随后用双官能亲电试剂对该二硫代化合物进行处理,从而可以制备各种苯并[ b ]杂环。
