Description

General description

Tetrabutylammonium iodide is a quaternary ammonium salt used in phase-transfer reactions. It is also used in regioselective ether cleavage reactions and as a source of iodide for nucleophilic displacement reactions.

Application

Tetrabutylammonium iodide can be used:

• As an additive in the synthesis of fused triazole derivatives using palladium catalyst.
• To prepare allyl-PEG-allyl, which is a key intermediate polymer used to synthesize fluorinated amphiphilic copolymers.
• As a catalyst used in the synthesis of ethers.
