Transition metal complexes of tetracyclines
Forty-one transition metals were studied to observe their complexing properties with the tetracyclines. Four metals were found to form sufficiently strong complexes with the tetracyclines to provide a basis for a rapid, reliable method of assaying the potency of the tetracycline products used in …

Transition metal complexes of pentadentate ligands
… B₁₂, I [see Figure I], represented below. These complexes might be expected to give some insight as to the behavior and role of the metal ion as it interacts with the five-donor atoms and hence an insight into the role of the metal ion in Vitamin B₁₂. [See Figure I] Compounds formed by the …

Transition Metal Complexes With Hydrosulfido and Thiophene Ligands
… to involve thiophene coordination to the metal surface and subsequent hydrogen transfer from a surface hydrosulfido group to the bound substate. Transitional metal complexes with SH or thiophene ligands may be thought of as molecular analogs of these proposed surface species.

Autonomous First-Principles Design of Transition Metal Complexes
Designing novel transition metal complexes (TMCs) holds immense potential for advancing sustainability and chemical synthesis. While high-throughput virtual screening (HTVS) workflows and density functional theory (DFT) have emerged as powerful tools for discovering new TMCs, exhaustive design …

Nitrene transfer reactions by late transition metal complexes
… reactions that are catalyzed or mediated by late transition metal complexes. Sterically large, fluorinated supporting ligands are used to minimize potential side reactions. A new 1,10-phenanthroline ligand has been synthesized with 2,4,6-(CF3)3C6H2- groups in the 2- and 9-positions (1). A cationic …

Transition Metal Complexes Anchored on Europium Oxide Nanoparticles
Polypyridyl transition metal complexes containing ruthenium, rhodium and iridium centers are mainly studied due to their light absorbing and emitting properties. Lanthanide oxides such as europium oxide absorb light as well and exhibit strong luminescence and long lifetimes. The optical properties …

Early Transition Metal Complexes Stabilized by Bulky Aminopyridinato Ligands
A series of early transition metal complexes stabilized by aminopyridinato ligands have been synthesized. Many of these complexes have been studied in terms of their structure and have been evaluated in terms of applications in catalysis. The overall evaluation tells about the importance of …

Design and Application of Transition Metal Complexes for Catalysis
… able to self-assemble and its application in the transition-metal asymmetric transfer hydrogenation (ATH) reaction of converting ketones to chiral alcohols in good yields and high enantiomeric excess. The third chapter highlights some of the unexpected observations encountered from several of our …
