Chemistry of Concerto Molecular Catalysis Based on the Metal/NH Bifunctionality
T. Ikariya
[Full Text PDF(J-STAGE)]
Free Access Article
 | The development of conceptually new bifunctional molecular catalysts based on metal–ligand cooperation is described. The concept of the bifunctional molecular catalysis is successfully applicable to asymmetric hydrogenation, dehydrogenative oxidation, and aerobic oxidation as well as enantioselective conjugate addition reactions. |

Free Access Article
Treatment of 3-alkyl-3-alkoxymethyloxetanes or 3-alkyl-3-siloxymethyloxetanes with trialkylsilanes in the presence of [Ru3{μ3-(η2,η3,η5-C12H8)}(CO)7] (1) led to ring-opening polymerization to afford functionalized polyoxetanes of Mn = 103–105. Chemical conversion of siloxy groups at the side chain afforded functionalized polyoxetanes.

[Full Text PDF(J-STAGE)]
[Supporting Information]
Open Access Article
We report that a macroscopic stretching operation can dynamically control the molecular conformation of a light-harvesting molecule in an elastomeric film; as a consequence, we have succeeded in controlling its photophysical function that is very much a molecular level phenomenon.

Theoretical Study of Hydrogen Chemisorption to Nitrogen-Substituted Graphene-Like Compounds
M. Kayanuma,* T. Ikeshoji, and H. Ogawa
[Full Text PDF(J-STAGE)]
Hydrogen chemisorption on nitrogen-substituted coronenes is investigated at MP2//HF level to assess hydrogen storage. Results showed that the interaction energy between hydrogen and model compounds strongly depends on both the substituted sites of N and adsorbing position of H2.

Derivation of Equations Describing Distance Solute Oscillation of Induced Solvent Polarization
P.-K. Yang
[Full Text PDF(J-STAGE)]
The $P_{\text{s}}^{\text{g}}(r)$
behaving as oscillating decay is observed from molecular dynamics simulations and cannot be reproduced from Gauss’s law of Maxwell’s equations. Here, the equations and an approximate analytical solution capturing the oscillating decay of $P_{\text{s}}^{\text{g}}(r)$
are derived for a spherical solute.

Influence of Electron-Donating and Electron-Withdrawing Substituents on the Chemiluminescence Behavior of Coelenterazine Analogs
R. Saito,* T. Hirano, S. Maki, H. Niwa, and M. Ohashi
[Full Text PDF(J-STAGE)]
[Supporting Information]
 | A series of coelenterazine analogs were synthesized to reveal the chemiluminescence maxima being substituent dependent. Chemiluminescence efficiencies were also proved to be substituent-sensitive, predominantly caused by the substituent-dependent fluorescence efficiencies of the light emitters. |

A novel clovane, rumphellclovane B (1), which possesses an unprecedented δ-lactone moiety, and a new natural clovane, 9α-hydroxyclovan-2-one (2), were isolated from Rumphella antipathies. The structures of 1 and 2 were elucidated by spectroscopic methods. A plausible biosynthetic pathway between these two compounds was proposed. Compound 1 displayed inhibitory effects on superoxide anion generation by human neutrophils.
