General description

Tetrabutylammonium phosphate monobasic solution (TABP) is a quaternary ammonium salt commonly used in the preparation of buffers and ion-pairing reagents.

Application

Tetrabutylammonium phosphate monobasic solution can be used as a:
  • Catalyst for the selective N-alkylation of indoles with electron-poor alkenes.
  • Hydrogen-bond-acceptor (HBA) catalyst to synthesize ketoesters via αC-H bond activation.

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
