Application

Tetrabutylammonium bisulfate (Bu4NHSO4) can be used as a reagent along with potassium fluoride dihydrate to synthesize β-fluoro amine derivatives by the ring-opening reaction of aziridines. It may also be utilized as a catalyst in the hydrolysis of aziridines and epoxides to corresponding β-amino alcohols and 1,2-diols, respectively.

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
