WebThe aldol reaction is a means of forming carbon–carbon bonds in organic chemistry. [1] [2] [3] Discovered independently by the Russian chemist (and Romantic composer) Alexander Borodin in 1869 [4] and by the French chemist Charles-Adolphe Wurtz in 1872, [5] [6] [7] the reaction combines two carbonyl compounds (the original experiments used ...

WebSufficient alcohol is used to dissolve the benzaldehyde rapidly and to retain the benzalacetone in solution until it has had time to react with the second molecule of aldehyde. Lower concentrations of base slow up the formation of the dibenzalacetone and thus favor side reactions which yield a sticky product. longman dictionary learnerWebAldol condensation is an important route of organic synthesis because it provides an efficient way to form carbon-carbon bond.
