Solventless aldol reaction
Webzeynep coban akdemir 🇺🇦 (@zcoban) / Twitter Free photo gallery The aldol reaction is a means of forming carbon–carbon bonds in organic chemistry. Discovered independently by the Russian chemist (and Romantic composer) Alexander Borodin in 1869 and by the French chemist Charles-Adolphe Wurtz in 1872, the reaction combines two carbonyl compounds (the original experiments used aldehydes) to form a new β-hydroxy carbonyl compo…
