A bridging monomer with terpyridine moieties at both ends of the insulated conjugated chain was successfully synthesized. The synthesis necessitated a new strategy, in which FeII was employed as a removable water-solubilizing substituent. The monomer was able to coordinate with FeII, CoII, NiII, or RuII to give highly insulated conjugated metallopolymers. The high-coverage insulation suppressed the recombination of charge carriers relative to an uninsulated reference and provided higher charge mobility along the chain than the less insulated metallopolymer.

The copper-catalyzed silylative allylation of ketones with allenes and silylboranes via an in situ generated β-silylallylcopper intermediate has been developed. Various ketones and allenes were con...

Magnesium chloride (MgCl2), a stable and cheap salt, works as an active catalyst for the synthesis of cyclic carbonates from epoxides and atmospheric-pressure carbon dioxide (CO2). Various epoxides are converted to the corresponding cyclic carbonates in good to high yields.

We synthesized cyclic host molecules, A, B, and C, based on a rigid π-conjugated system composed of porphyrin and fluorene units. After the transformation of the ester units of cyclic host B to car...

Expanding catalytic environment to a nanosize is one of the most promising ways to improve performance of homogeneous catalysts. In this highlight review, recent development in homogeneous transiti...

Ru3(CO)12 showed high catalytic activity for the deoxygenation of various ketoximes to the corresponding ketimines under carbon monoxide pressure (20 kg/cm2). For the deoxygenation of propiophenone oxime, ethyl phenyl ketimine was obtained in 100% yield. On the other hand, heptanal oxime which was aldoxime was dehydrated under the same reaction conditions to the corresponding nitrile in 32% yield.

A Pt–alkynyl polymer in which the π-conjugated chain was completely covered with macrocycles was synthesized by intramolecular self-inclusion of an oligomeric phenyleneethynylene as a guest moiety ...

Linked symmetric [3]rotaxanes consisting of an oligomeric phenylene–ethynylene (OPE) unit as a π-conjugated guest and two molecules of organic soluble permethylated α-cyclodextrins (PM α-CDs) as ma...

Methanol reacts with aminoarenes in the presence of a catalytic amount of ruthenium trichloride hydrate combined with tributylphosphite at 180 °C to give the corresponding N-methylaminoarenes in high yields.

Amines reacted with primary alcohols in the presence of a platinum complex catalyst at 120–180 °C to give N-alkylated or N-allylated compounds.

An equimolar mixture of a ketone and formic acid was heated without solvent at 125°C for 3 h in the presence of a catalytic amount of dichlorotris(triphenylphosphine)ruthenium(II) to give the corresponding secondary alcohols in excellent yields.

Platinum complex combined with SnCl2·2H2O activates a primary amine and catalyzes the transformation to the secondary amine at 180 °C. Dibutylamine was obtained from butylamine in 74% yield.
