Publikováno v: Beilstein Journal of Organic Chemistry, Vol 15, Iss 1, Pp 2277-2286 (2019)

We report the synthesis of a new bistriarylamine series having a urea bridge and investigate its mixed-valence (MV) states by electrochemical and spectroelectrochemical methods. We found that the supporting electrolytes had unusual effects on potenti

Learning from B12 enzymes: biomimetic and bioinspired catalysts for eco-friendly organic synthesis

Autor: Keishiro Tahara, Ling Pan, Toshikazu Ono, Yoshio Hisaeda

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 14, Iss 1, Pp 2553-2567 (2018)

Cobalamins (B12) play various important roles in vivo. Most B12-dependent enzymes are divided into three main subfamilies: adenosylcobalamin-dependent isomerases, methylcobalamin-dependent methyltransferases, and dehalogenases. Mimicking these B12 en

Publikováno v: Crystals, Vol 11, Iss 8, p 868 (2021)

We report the structural and physical properties of a new organic Mott insulator (BEDT-BDT)AsF6 (BEDT-BDT: benzo[1,2-g:4,5-g′]bis(thieno[2,3-b][1,4dithiin). This AsF6 salt has the same structure as the PF6 salt. Although the anions are disordered,
