설명

애플리케이션

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.
