Application
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.
