Description

General description

Tetrapentylammonium bromide is a quaternary ammonium salt with pentyl chains and a bromide counterion, which is generally used as a phase transfer catalyst.

Application

Tetrapentylammonium bromide can be used:

• As a versatile structure-directing agent for the synthesis of Zeolite-like heterobimetallic cyanide frameworks.
• As an alkylating agent for rhodium(I)-catalyzed alkylation reaction of benzylic amines and for N-alkylation of azaheterocycles.
• As a precursor to prepare a Cobalt-complex, {[(Pentyl)₄N]₃CoBr₃}Cl₂, which is used as a catalyst in the synthesis of multiwalled carbon nanotubes (MWCNTs).

Electrochemical synthesis of stable graphite intercalation compounds (GICs) containing tetrapentylammonium cations has been reported.
