Wilhelm Rudolph Fittig (1835 – 1910) was a German chemist. He obtained his Ph.D. in 1858 in Göttingen. Fittig was responsible for discovery of the pinacol coupling reaction, mesitylene, diacetyl and biphenyl. He studied the action of sodium on ketones and hydrocarbons. He discovered the Fittig reaction or Wurtz-Fittig reaction for the synthesis of alkylbenzenes, he proposed a diketone structure for benzoquinone and isolated phenanthrene from coal tar. He discovered and synthesized the first lactones and investigated structures of piperine naphthalene and fluorene. | Come and take it, slogan of the Texas Revolution 1835 was a common year starting on Thursday (see link for calendar). ... -1...
