Application

Zirconium (IV) chloride acts as an efficient Lewis acid catalyst for various reactions; such as:
  • electrophilic addition reaction of indole with aldehydes/ketones to form bis(indolyl)methanes. electrophilic amination of activated arenes,
  • transthioacetylization of acetals,
  • deoxygenation of heterocyclic-N-oxides,
  • reduction of nitro compounds,
  • conversion of carbonyl compounds to 1,3-oxathiolanes,
  • Biginelli reaction for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones,
  • direct amide coupling of non activated carboxylic acids and amines,
  • synthesis of quinoxalines and pyrido[2,3-b]pyrazines,
  • deprotection of t-butyldimethylsilyl (TBDMS) ethers.
Activates pyrrolidines for improved conversion, via a modified Bouveault reaction, to the corresponding α,α-dimethylamines.
