Description

Application

Tetraethylammonium cyanide can be used:

• As a cyanide source for 1,4-addition of cyano group to enones (chalcones) catalyzed by scandium(III) triflate to yield β-cyanoketones.
• Along with diethylazodicarboxylate (DEAD) in the regioselective C- or N- ethoxy-carbonylation of heterocyclic systems like indoles and indazoles.
• In the synthesis of C-C-bridged bis-isoflavones from 2-bromomethyl-7,4′-dimethoxyisoflavone.

Tetraethylammonium cyanide is a versatile reagent commonly used in cyanation reactions as cyanide source. It is also used in the preparation of various cyanometalate complexes.
