Imada, Yasushi,Shida, Naoki,Okada, Yohei,Chiba, Kazuhiro
, p. 557 - 560 (2019)
The discovery that lithium bis(trifluoromethane)sulfonamide (LiTFSI)/1-nitropropane (PrNO2) solution functions as a less polar alternative to lithium perchlorate (LiClO4)/nitromethane (MeNO2) solution has led to the develo
Mechanistic Insights on Concentrated Lithium Salt/Nitroalkane Electrolyte Based on Analogy with Fluorinated Alcohols
Chiba, Kazuhiro,Imada, Yasushi,Okada, Yohei,Shida, Naoki
, p. 570 - 574 (2020)
Fluorinated alcohols such as 1,1,1,3,3,3-hexafluoro2-propanol (HFIP) and 2,2,2-trifluoroethanol (TFE) have emerged as powerful solvents in oxidation chemistry including hole catalysis. In this paper, we describe the similarity of lithium salt/nitroalkane
Visible-Light-Irradiated Graphitic Carbon Nitride Photocatalyzed Diels–Alder Reactions with Dioxygen as Sustainable Mediator for Photoinduced Electrons
Zhao, Yubao,Antonietti, Markus
, p. 9336 - 9340 (2017)
Photocatalytic Diels–Alder (D–A) reactions with electron rich olefins are realized by graphitic carbon nitride (g-C3N4) under visible-light irradiation and aerobic conditions. This heterogeneous photoredox reaction system is highly e
Entropic electrolytes for anodic cycloadditions of unactivated alkene nucleophiles
Imada, Yasushi,Yamaguchi, Yusuke,Shida, Naoki,Okada, Yohei,Chiba, Kazuhiro
, p. 3960 - 3963 (2017)
Unactivated alkenes were previously found to be effective carbon nucleophiles for anodic cycloadditions in lithium perchlorate/nitromethane electrolyte solution. Herein,7Li NMR analysis and calorimetric studies clearly illustrate that the entro
Photocatalytic Cycloadditions Enabled by a Lithium Perchlorate/Nitromethane Electrolyte Solution
Nagahara, Shingo,Wakamatsu, Hiroki,Okada, Yohei,Chiba, Kazuhiro
, p. 6720 - 6723 (2018)
Photocatalytic cycloadditions involving carbon–carbon bond formation in the absence of an external sensitizer are described. The use of a lithium perchlorate/nitromethane electrolyte solution exhibiting remarkable Lewis acidity is the key for the successf

This report details the synthesis and characterization of a small family of previously unreported, structurally related chromium, molybdenum, tungsten, manganese, and iron complexes bearing N-heterocyclic carbene and carbonyl supporting ligands. These complexes have the general form [ML(CO)3X] or [ML(CO)3], where X = CO or Br and L = 1-phenyl-3-(2-pyridyl)imidazolin-2-ylidene. Where possible, the solid-state, spectroscopic, electrochemical, and photophysical properties of these molecules were studied using a combination of experiment and theory. Photophysical studies reveal that decarbonylation occurs when these complexes are exposed to ultraviolet light, with the CO ligand being replaced with a labile acetonitrile solvent molecule. To obtain insights into the potential utility, scope, and applications of these complexes in visible-light-mediated photoredox catalysis, their capacity to facilitate a range of photoinduced reactions via the reductive or oxidative functionalization of organic molecules was investigated. These chromium, molybdenum, and manganese catalysts efficiently facilitated atom-transfer radical addition processes. In light of their photolability, these types of catalysts may potentially allow for the development of photoinduced reactions involving less conventional inner-sphere electron-transfer pathways.
