应用
氰化四丁基胺可用作催化剂：
- 在质子溶剂存在下，用于脱保护脂肪族硫醋酸酯，以合成自由硫基
- 在三甲基氰硅烷（TMSCN）存在下，用于羰基化合物的O-TMS 氰硅化反应，以合成氰丙烷三甲基硅醚.
- 在乙腈的存在下，通过对β-内酰胺键裂合成γ内酰胺，进而实现β-内酰胺的环扩展.

Tetrabutylammonium cyanide (20 mol %) catalyzes ring expansion of 4-(arylimino)methylazetidin-2-ones 2 to 5-aryliminopyrrolidin-2-ones 3 through a novel N1-C4 bond cleavage of the beta-lactam nucleus. New, efficient one-pot protocols to enantiopure succinimide derivatives 3 and 4 from beta-lactam aldehydes 1 have

A new series of tris(2-aminoethyl)amine (tren)-based L-alanine amino acid backboned tripodal hexaamide receptors (L1-L5) with various attached moieties based on electron-withdrawing fluoro groups and lipophilicity have been synthesized and characterized. Detailed binding studies of L1-L5 with different anions, such as

The conversion of 3',5'-disilylated 2'-O-(methylthiomethyl)ribonucleosides to 2'-O-(phthalimidooxymethyl)ribonucleosides is achieved in yields of 66% to 94%. Desilylation and dephtalimidation of these ribonucleosides by treatment with NH(4)F in MeOH produce 2'-O-aminooxymethylated ribonucleosides, which are efficient in producing stable and yet reversible 2'-conjugates
