Merck, 310468-100G, Lithium chloride

General description
Lithium chloride (LiCl) is a lithium salt. It is used as a source of chloride nucleophile as well as a source of chloride ligand in chemical synthesis. LiCl is also used as a desiccant in drying air streams.
Application
Lithium chloride can be used as:
A source of chloride anion for the conversion of alcohols to alkyl chloride under Mitsunobu conditions.
An additive in the palladium-catalyzed coupling and carbonylative coupling reactions of organostannanes and vinyl triflates.
A reagent for the cleavage of protecting groups under mild conditions. It readily converts acetals and ketals to the corresponding carbonyl compounds.
A reagent in the dehydrohalogenation of α-halocarbonyl compounds to α,β-unsaturated carbonyls compound in the presence of DMF.

LiCl is also used with other reagents:
LiCl:DIPEA (1:1 molar ratio) is used in Horner–Wadsworth–Emmons alkenation reaction.
LiCl:Hexamethylphosphoric triamide is used in decarboxylative alkylation and chloride displacement reactions.
LiCl is used as an additive in solid-phase peptide synthesis because it increases resin swelling and improves the efficiencies of complex coupling steps.

Features and Benefits
