应用 氰化四乙基铵是一种多用途试剂，常被用作氰化反应的氰化物源。它还被用于制备各种氰基金属配合物。氰化四乙基铵可用于：在三氟甲基磺酸钪(III)的催化下，作为氰基与烯酮（查尔酮）的1,4-加成反应以生成β腈酮的氰化物来源。与偶氮二甲酸二乙酯(DEAD)一起在吲哚和吲唑等杂环系统中进行区域选择性C-或N-乙氧基羰基化反应。通过2-溴甲基-7,4′-二甲氧基异黄酮合成C-C桥双异黄酮。 Description 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.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- orN- ethoxy-carbonylation of heterocyclic systems like indoles and indazoles.In the synthesis of C-C-bridged bis-isoflavones from 2-bromomethyl-7,4′-dimethoxyisoflavone.
