…The Wurtz reaction itself is a symmetrical hydrocarbon synthesis reaction, but in 1864 Rudolf Fittig (1835-1910) applied this reaction to the coupling reaction of aromatic halides (aryl halides, ArX in the following formula) with alkyl halides. This is known as the Wurtz-Fittig reaction (or simply the Fittig reaction). In this case, ArX is preferentially metallated to produce ArNa, so the R-Ar coupling product is preferentially produced. … *Some of the terminology explanations that mention the "Wurtz-Fittig reaction" are listed below.

…ウルツ反応自身は対称な炭化水素の合成反応であるが,フィティヒRudolf Fittig(1835‐1910)は64年この反応を芳香族ハロゲン化物(ハロゲン化アリール,次式のArX)とハロゲン化アルキルとのカップリング反応に応用した。これはウルツ=フィティヒ反応(単にフィティヒ反応ともいう)として知られる。この場合,ArXが優先的にメタル化されてArNaが生ずるので,R-Arのカップリング生成物が優先的に生成する。… ※「ウルツ=フィティヒ反応」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
