Application

Tetrabutylammonium iodide can be used:
  • As an additive in the synthesis of fused triazole derivatives using palladium catalyst.
  • To prepare allyl-PEG-allyl, which is a key intermediate polymer used to synthesize fluorinated amphiphilic copolymers.
  • As a catalyst used in the synthesis of ethers.

General description

Tetrabutylammonium iodide is a quaternary ammonium salt used in phase-transfer reactions. It is also used in regioselective ether cleavage reactions and as a source of iodide for nucleophilic displacement reactions.

The complex cis-[Ru(phpy)(phen)(CH3CN)2](+) (phpy=2-phenylpyridine, phen=1,10-phenanthroline) was investigated as a potential photodynamic therapy (PDT) agent. This complex presents desirable photochemical characteristics including a low energy absorption tail extending into the PDT window (600-850nm) and photoinduced exchange of the CH3CN ligands, generating
