Studies on Catalytic Activation of Olefins Using Cobalt Complex.
In this review, I tell the story of the cobalt chemistry that has been developed in my group since 2011. First, we achieved the total synthesis of polyketide natural product trichodermatide A, which involved a late-stage Isayama-Mukaiyama hydration of an enol ether using cobalt(II) acetylacetonate (Co(acac)2) that gave the desired product chemo-, regio-, and diastereoselectively. After our repo...

متن کاملThe distribution of radioactive cobalt in pigs.
The discovery (Smith, 1948; Rickes, Brink, Koniuszy, Wood & Folkers, 1948) that vitamin B,, contains cobalt immediately suggested that it might be possible to label the molecule with radioactive cobalt. A radioactive form of the vitamin would be invaluable for many biochemical investigations. However, as was rather to be anticipated from earlier experiments (Flagg, 1941; McCallum & Hoshowsky, 1...
متن کاملAcid denaturation studies on a cobalt(3) protoporphyrin-globin complex.
A cobalt (III)-protoporphyrin IX complex of horse globin (cobaltiglobin) has been prepared and its stability toward acid denaturation determined. Unlike iron(II1) protoporphyrin, which combines with. globin to give ferrihemoglobin, cobalt(II1) protoporphyrin combines with globin to give a complex which experimentally resembles an internal ferrihemichrome in which the heme is attached to the pro...
متن کاملSurface-Induced Changes in the Thermochromic Transformation of an Ionic Liquid Cobalt Thiocyanate Complex
We demonstrate that a thermodynamic complex equilibrium within an ionic liquid film can be significantly influenced by the presence of the liquid-vacuum interface. Using surface-sensitive X-ray photoelectron spectroscopy, we find that the temperature-driven transition from the blue-colored tetrahedral [Co(II) (NCS)4]2- to the red-colored octahedral [Co(II) (NCS)6]4- complex already occurs withi...
