What is Ciamician-Dennstedt rearrangement? The Ciamician-Dennstedt rearrangement is a chemical reaction that involves the transformation of a pyrrole ring (a five-membered ring) into a six-membered ring by heating it in an alkaline solution with chloroform, CHCl3, or other halogeno compounds. During the reaction, an intermediate product called dichlorocarbene CH2Cl2 is formed, which then reacts with the … Read more
What is Suárez reaction? The Suárez reaction, also known as Suárez fragmentation or Suárez cleavage, involves the photoinduced conversion of hydroxyl-containing substrates with hypervalent iodine I(III) I2, resulting in the formation of the corresponding oxygen-centered radical (see list of acronyms).

What is Houben-Hoesch reaction? This reaction was first reported by Hoesch in 1915 and was extended subsequently by Houben in 1926. The Houben-Hoesch reaction is also referred to as the Hoesch synthesis, Houben-Hoesch condensation, Houben-Hoesch acylation, Houben-Hoesch synthesis, or Hoesch reaction. Moreover, the intramolecular version of such reaction is also known as the Houben-Hoesch cyclization. This Houben-Hoesch reaction involves … Read more
