Prins reaction :
The condensation reaction of alkenes with aldehydes in presence of acid is referred to as the Prins reaction.
Name Reaction
Pomeranz-Fritsch Reaction
Pomeranz-Fritsch Reaction is acid-catalyzed Synthesis of isoquinoline by heatingcyclization of benzalaminoacetals (these are Schiff bases) to give substituted isoquinolines is known as the Pomeranz-Fritsch reaction.
Baker-Venkataraman Rearrangement
Baker-Venkataraman Rearrangement is the base-promoted (KOH) rearrangement of aromatic 2-acyloxy ketones to the corresponding aromatic 1,3-diketone (β-diketones)
Prilezhaev Reaction:
This transformation is referred to as the Prilezhaev reaction for synthesis of oxiranes (epoxides) from isolated double bonds by using peroxycarboxylic acids as oxidizing agents. This method provides products in racemic mixture form.
Prins-Pinacol Rearrangement :
The formation of oxacyclic and carbocyclic ring systems by terminating Prins cyclizations with the pinacol rearrangement in a tandem fashion is known as the Prins-pinacol rearrangement.
Reimer-Tiemann Reaction : Mechanism, Application, Examples
The Reimer-Tiemann reaction is an organic transformation that converts a phenol into an 2-hydroxy benzaldehyde using chloroform, a base, and an acid work-up at last step. Reimer-Tiemann Reaction Mechanism: The reaction commences with removing a proton from chloroform by the base, forming a trichlorocarbanion. This intermediate, however, spontaneously eliminates a chloride ion, generating a neutral … Read more
