A survey of acid catalysts in dipyrromethanecarbinol condensations leading to meso-substituted porphyrins

10.1002/jpp.387

2001-12-31

The successful use of dipyrromethanecarbinols in rational routes to porphyrinic macrocycles requires catalysis conditions that enable irreversible condensation, thereby avoiding substituent scrambling and formation of undesired porphyrin products. Previously,...

Evaluation studies of technetium-99m-porphyrin (T3,4BCPP) for tumor imaging

10.1002/jpp.546

2001-12-31

A water-soluble porphyrin, 5,10,15,20-tetrakis[3,4-bis(carboxymethyleneoxy)phenyl] porphyrin (T3,4BCPP), was successfully labeled with 99mTc and biodistribution studies were performed in Wistar rats. Scintiimaging and in vivo distribution studies were also ca...

Kinetics of zinc ion incorporation in base into a centrally aprotic beta-octabrominated cationic water-soluble porphyrin and its monolithium complex

10.1002/jpp.549

2001-12-31

The kinetics of zinc incorporation from pH 12 to 13 into the centrally aprotic BrP(4)2+ form of beta-octabromo-meso-tetrakis(N-methyl-4-pyridyl)porphyrin and its monolithium complex were studied at 25.0 °C, ionic strength (I) = 0.10. The reactions were first ...

Synthesis of N-phytochlorin-substituted [60]fulleropyrrolidines

10.1002/jpp.550

2001-12-31

A series of new phytochlorin–fullerene dyads was prepared. Synthetic pathway includes attachment of glycine to aldehyde-containing phytochlorins via reductive amination, where 3- and 7-carbonyl-substituted pheophorbides exhibit surprisingly different reactivi...

Spectroscopic studies of the interaction of cobalt(II) N,N′,N″,N″′-tetramethyltetra-3,4-pyridinoporphyrazine with amino acids and nitrogen oxides

10.1002/jpp.551

2001-12-31

The interaction of histidine, cysteine, NO and nitrite with cobalt(II) N,N′,N″,N″′-tetramethyltetra-3,4-tetrapyridinoporphyrazine ([CoIItmtppa]4+) is reported. Metal-based autoreduction of [CoIItmtppa]4+ occurs with the formation of the [CoItmtppa(−2)]3+ spec...

A non-tetradecarboxylative synthesis of ­2,7,12,17-tetraphenylporphycene

10.1002/jpp.552

2001-12-31

A new synthetic method for 2,7,12,17-tetraphenylporphycene (2e, TPPo) which avoids tetradecarboxylation by sublimation of the intermediate tetracarboxylic acid 8 is reported. Thus, the use of a pyrrol 13a bearing two orthogonal ester groups allows the synthes...

PDT-related photophysical properties of conformationally distorted palladium(II) porphyrins

10.1002/jpp.553

2001-12-31

The photodynamic therapy (PDT) related photophysical properties of five palladium(II) porphyrins with increasing steric demand of the meso-substituents were investigated by steady state and time-resolved absorption and luminescence spectroscopy. The steric st...

5,15-Diaryl-β-substituted-porphyrinato-manganese(III) chlorides as probes for structure–activity relationships in porphyrin-based epoxidation catalysts

10.1002/jpp.554

2001-12-31

Manganese complexes of 5,15-diaryl-β-substituted-porphyrins were prepared and their behaviour as oxidation catalysts was studied. The role of the pyrrolic and meso-substituents on the activity and selectivity of these catalysts was studied to reveal new struc...

Synthesis of organo-soluble metallophthalocyanines bearing electron-withdrawing substituents

10.1002/jpp.556

2001-12-31

The syntheses of organo-soluble metallophthalocyanines having sulfo- and sulfonamido- electron-withdrawing substituents are reported. The simple cation exchange of the readily available tetrasodium salt of metallo-sulfophthalocyanines 1 (M = Ni, Co, Fe, Cr) b...
