Singly and doubly β-to-β platinum-bridged porphyrin dimers and their reductive eliminations
2-Borylated porphyrins reacted with Pt(cod)Cl2 to give b-to-b platinum-bridged porphyrin dimers, which were converted to b-to-b directly linked porphyrin dimers through triphenylphosphine-mediated reductive elimination. Similar reactions of 2,18-diborylated Ni(II)–porphyrin and Zn(II)–porphyrin gave the corresponding doubly b-to-b platinum-bridged porphyrin dimers. Treatment of the doubly b-to-...

A series of novel luminescent platinum(II) complexes bearing orthometalated 2-phenylpyridine ligands (C N), namely 2-phenylpyridine (4) and 3-hexyloxy-2-phenylpyridine (5), and several 5-substituted quinolinolate ligands (5-X-Q), where X = NO2 (a), X = CHO (b), X = Cl (bearing another Cl in 7-position of the Q-ligand) (c) and X = H (d) have been synthesized, characterized and their photophysica...

متن کاملSynthesis of Cis-Diammine (1,1-cyclobutane dicarboxylate) Platinum(II)
Platinum-based anticancer drugs are chemotherapeutic agents to treat cancer. Carboplatin (cis diammine cyclobutane dicarboxylate platinum (II)) is a second generation drug that has less toxic than cisplatin, allowing for high dosages. In the first stage, 1,3-Cyclobutane dicarboxylic acid, a key intermediate for the preparation of carboplatin, have been synthesized in good yields using diffe...
متن کاملA comparative study of the interaction of platinum with group 4A (germanium, tin and lead) porphyrins.
Because of its vast number of applications and high price many studies have been made on how to reduce the amount of platinum in catalysts. One method includes dispersing platinum nanoparticles in porous support materials. But electrically conductive carbon-based support materials-needed for fuel cell electrodes-permit nanoparticles to migrate and form larger clusters, leading to reduced cataly...
