DESCRIPTION
Aplication
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.
