Practical Aerobic Oxidations of Alcohols and Amines with Homogeneous Copper/TEMPO and Related Catalyst Systems

Practical Aerobic Oxidations of Alcohols and Amines with Homogeneous Copper/TEMPO and Related Catalyst Systems

Coming up for air: Cu/nitroxyl catalysts for aerobic alcohol oxidation have been developed that exhibit near-ideal reaction conditions: operation at room temperature, use of ambient air as the oxidant, and complete reaction within one hour. These methods, together with related amine oxidations, have the potential to be the first class of aerobic oxidation reactions widely used in organic chemistry.

Design of Superhydrophobic Porous Coordination Polymers through the Introduction of External Surface Corrugation by the Use of an Aromatic Hydrocarbon Building Unit

Design of Superhydrophobic Porous Coordination Polymers through the Introduction of External Surface Corrugation by the Use of an Aromatic Hydrocarbon Building Unit

A strong aversion to water: In an approach to water-resistant porous materials with a superhydrophobic surface without the use of alkylation or fluorination, a porous coordination polymer was synthesized with a low-symmetry nanoscale organic linker. The material exhibited superhydrophobicity (see picture) as a result of the surface corrugation created by the aromatic hydrocarbon and displayed selective uptake of organic molecules from water.

Aza-[4+3] and Aza-[3+2] Annulations for Synthesis of Dihydroazepines and Dihydropyrroles from Alkynes, Sulfonyl Azides, and 1,3-Dienes

We have developed aza-[4+3] annulation via successive [3+2]-[2+1] cycloaddition-aza-Cope rearrangement for the synthesis of dihydroazepines. Aza-[3+2] annulation was accomplished via [3+2]-[2+1]-aza-Cope rearrangement-1,3-migration or [3+2]-[2+1]-Clock rearrangement to give dihydropyrroles along with molecular nitrogen. This procedure was applied to a one-pot process starting from terminal alkynes, azides, and dienes.

Ring Opening and Bidentate Coordination of Amidinate Germylenes and Silylenes on Carbonyl Dicobalt Complexes: The Importance of a Slight Difference in Ligand Volume

Ring Opening and Bidentate Coordination of Amidinate Germylenes and Silylenes on Carbonyl Dicobalt Complexes: The Importance of a Slight Difference in Ligand Volume

A bit bulkier is too much: A combined experimental and computational DFT study has shown that the terminal to bridging transformation of an amidinate–tetrylene unit on a dicobalt carbonyl complex is negligibly influenced by the nature of the tetrylene Group 14 donor atom (Si or Ge; see figure), but is strongly dependent upon the steric hindrance exerted by the amidinate N-R groups because the reaction is thermodynamically favorable for R=iPr but not for R=tBu.

Competing Reactions of CO2 with Cations and Anions in Azolide Ionic Liquids

Two different paths: Phosphonium azolide ionic liquids of interest for CO2 capture applications react with CO2 both through the normal anion channel and, at elevated temperatures, through a previously unrecognized cation channel. The cation channel involves a phosphonium ylide intermediate that is formed due to cation/anion interactions. This channel is suppressed with less-acidic ammonium cations.

Silica Mineralization by a Peptide Template Having a High Charge Relay Effect

Silica Mineralization by a Peptide Template Having a High Charge Relay Effect

In charge: The influence of the charge relay effects of peptide organic templates on silica mineralization has been investigated. β-Sheet-type peptide shows higher catalytic activity toward the condensation of trimethylsilanol than random-coil peptide (see figure). Silica mineralized on the Val-His-Val-Glu-Val-Ser (VHVEVS) peptide template forms a flat surface, which is affected by the peptide morphology.

Shielding of a Microdisc Electrode Surrounded by an Adsorbing Surface

Shielding of a Microdisc Electrode Surrounded by an Adsorbing Surface

Sheath shielding: It is shown that if significant adsorption occurs on the sheath used to insulate a microdisc electrode, then it can have a high impact on the measured current–time data because of a considerable shielding effect. Chronoamperograms are simulated as a function of the sheath-to-disc electrode radius ratio and the rate constant for adsorption onto the sheath.

Macroscopic Control of Helix Orientation in Films Dried from Cholesteric Liquid-Crystalline Cellulose Nanocrystal Suspensions

Macroscopic Control of Helix Orientation in Films Dried from Cholesteric Liquid-Crystalline Cellulose Nanocrystal Suspensions

Film star: A new method for drying cholesteric liquid-crystalline cellulose nanocrystal suspensions into solid films avoids phase coexistence and, with an applied circular shear flow, yields unprecedented structural control. The commonly observed mosaic-like structure, with randomly varying orientation of the cholesteric helix axis, is replaced by a macroscopically uniform film with improved optical properties (see figure).

Isomerism of Cycloserine and Its Protonated Form

Isomerism of Cycloserine and Its Protonated Form

Pucker up: The gas-phase isomerism of cycloserine and its protonated forms was investigated computationally and experimentally by IR multiphoton dissociation spectroscopy. The isomers of cycloserine show pronounced ring puckering, which generates rich conformeric landscapes (see figure). The relative stability of the various isomers responds to a balance between attractive and repulsive interactions among the functional groups of the molecule.
