Tetraphenylporphyrinato

A further interesting application of CLM involves the fluorescence quenching reaction between (5,10,15,20-tetraphenylporphyrinato) zinc (II) and methylviologen at a dode-cane-water interface. [62] This study demonstrated that the quenching reaction could occur only in the presence of an anionic surfactant, sodium dodecyl sulfate (SDS). The quenching efficiency depended on the concentration of SDS in the aqueous phase with a maximum value of 13.5%...

Scheme 6.14 Proposed mechanism for the formation of hydroxycarbamates from secondary aliphatic amines, C02 and epoxides catalyzed by AI(TPP)(02CCH3) [(5,10,15,20-tetraphenylporphyrinato)aluminum(lll) acetate].

The endoperoxide transfers a sulfur atom to alkenes forming thiiranes (episulfides) the process is made more efficient in the presence of the tetraphenylporphyrinato cobalt(ll) complex <1996CC177>. With cyclic alkynes such as cyclooctyne, an interesting thiirenium ion intermediate could be observed <2002JA8316>. 

In some cases, matrix-isolation laser-Raman spectroscopy can be utilized to produce unstable species via laser photolysis and to measure their resonance Raman spectra simultaneously in the same matrix using the same laser. For example, Proniewicz et al. (93) measured the resonance Raman spectra of Fe(TPP—d%) (TPP—d% analogue of tetraphenylporphyrinato anion) in O2...

The synthesis, spectroscopic, and stmctnral characterization of the stable Ga hydride porphyrin [Ga(TPP)H] (TPP = 5,10,15,20-tetraphenylporphyrinato) was synthesized in high yield (85%) by reducing [Ga(TPP)Cl] with NaBH4 in DMF. Infrared (IR) studies determined the Ga-H stretch at 1864 cm and the hydride H NMR resonance located at -6.47ppm. The Ga-H distance is 1.48(4) A, whereas the Ga atom lies 0.46(1) A from the perfect porphyrin plane. ...
