[Full Text PDF(J-STAGE)]

A multi-pH generalized ensemble simulation method is proposed; it is applied to the titration of the model weak polyelectrolyte. The first-order coil–globule transition is found in a poor solvent case. The conformation of the transition state is closely examined.

[Full Text PDF(J-STAGE)]

We prepared and fully characterized a conductive–paramagnetic bifunctional room-temperature ionic liquid [EMI][FeIIICl4], which shows an ionic conductivity of 1.8 × 10−2 S cm−1 and a static susceptibility of 1.4 × 10−2 emu mol−1 at room temperature.

[Full Text PDF(J-STAGE)]

Peptides possessing the DNA-binding capability were successfully introduced into myoglobin by a cofactor-reconstitution strategy.

[Full Text PDF(J-STAGE)]

We fabricated organic light-emitting diodes from horse-heart cytochrome c, and measured the electroluminescence spectra. The external quantum efficiency almost linearly increased for the applied voltages above 6 V and reached to 6–8 × 10−8 at an applied voltage of 13 V.

1401-1410 Facile Synthesis of Aryl- and Alkyl-bis(trifluoromethylsulfonyl)methanes
Best of the Month

[Full Text PDF(J-STAGE)]

Aryl- and alkyl-bis(trifluoromethylsulfonyl)methanes can be easily synthesized from the corresponding benzylic halides and alkyl alcohols, respectively. In addition, pentafluorophenylbis(trifluoromethylsulfonyl)methane can be reacted with alkyl lithiums and sodium alkoxides at para-position.

1206-1217 Cycloaddition of “N-Acyliminium Ion Pools” with Carbon–Carbon Multiple Bonds
Best of the Month

[Full Text PDF(J-STAGE)]  [Supporting Information]

N-Acyliminium ion pools generated by the “cation pool” method were found to react with a variety of alkenes and alkynes to give the corresponding cycloadducts.

977-987 Synthesis of Kinetically Stabilized 1-Silanaphthalenes and Their Properties
Best of the Month

[Full Text PDF(J-STAGE)]

Kinetically stabilized 1-silanaphthalenes are synthesized by taking advantage of efficient steric protection groups, Tbt and Bbt. In spite of such high aromaticity, Tbt-substituted 1-silanaphthalene has high and unique reactivities toward various reagents.

[Full Text PDF(J-STAGE)]

We have developed calix[5]arene-based receptors for dumb-bell-shaped C120. The receptors encapsulate C120 with the high binding constants in o-dichlorobenzene.

591-598 14 Step-15 Electron Reversible Redox Behavior of Tetrameric Oligomer of Oxo-Bridged Triruthenium Cluster
Best of the Month

[Full Text PDF(J-STAGE)]

A well separated reversible multistep, multi-electron redox system consisting of pyrazine-bridged oxo-centered triruthenium clusters was designed and synthesized through careful selection and arrangement of the ancillary ligands on the ruthenium clusters.

[Full Text PDF(J-STAGE)]

Rate constants for triplet–triplet annihilation of dendric multiporphyrin arrays and for electron transfer vs C60 were evaluated by the transient absorption methods and the observed rate constants were interpreted by the proposed kinetic models.

67-87 Synthesis, Structures, and Reactions of Coordinatively Unsaturated Trinuclear Ruthenium Polyhydrido Complexes, [{Ru(C5Me5)}3(μ-H)6](Y) (Y = BF4, CF3SO3, 1/2(SO4), C6H5CO2, CH3CO2, B(C6H5)4, PF6) and [{Ru(C5Me5)}3(μ-H)3(μ3-H)2]

Coordinatively unsaturated triruthenium pentahydride, [{Ru(C5Me5)}3(μ-H)3(μ3-H)2], underwent H/D exchange with deuterated aromatic compounds via an intermediary η2-arene complex, and reacted with active small molecules, such as O2, CH3I, and CO, with retention of the Ru3 framework.
