Tetrabutylammonium cyanide can be used as a catalyst:
- For the deprotection of aliphatic thioacetate to synthesize free thiols in the presence of a protic solvent.
- In the O-TMS cyanosilylation of carbonyl compounds to synthesize cyanohydrin trimethylsilyl ethers in the presence of trimethylsilyl cyanide (TMSCN).
- For the ring expansion of β-lactams to synthesize γ-lactams through a bond cleavage of the β-lactam in the presence of acetonitrile.

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

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

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
