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.
