Synthetic chemistry with nitrous oxide and triazenes

Nitrous oxide (N2O) has gained much interest because of its physiological effects ("laughing gas") and its negative environmental impact ("greenhouse gas", "ozone-depleting substance"): It has a lifetime of more than 100 years in the atmosphere. Its persis ...

Hydrothermally Stable Sulfonated Carbons as Solid Acid Catalysts for the Hydrolysis of Lignocellulose

David Ferdinand Scholz

The recycling of homogeneous acids imposes great challenges to the feasibility of lignocellulose hydrolysis processes. Although heterogeneous catalysts would offer a perspective to circumvent these challenges, conventional solid acids are instable under th ...

Characterization of aerosol composition, aerosol acidity, and organic acid partitioning at an agriculturally intensive rural southeastern US site

Athanasios Nenes, Yixing Chen, Hairun Guo

The implementation of stringent emission regulations has resulted in the decline of anthropogenic pollutants including sulfur dioxide (SO2), nitrogen oxides (NO x), and carbon monoxide (CO). In contrast, ammonia (NH3) emissions are largely unregulated, wit ...

Amidation of Aldehydes and Alcohols through α-Iminonitriles and a Sequential Oxidative Three-Component Strecker Reaction/Thio-Michael Addition/Alumina-Promoted Hydrolysis Process to Access β-Mercaptoamides from Aldehydes, Amines, and Thiols

Qian Wang, Jieping Zhu, Jean-Baptiste Gualtierotti, Xavier Schumacher

Mild and general alumina promoted hydrolysis conditions for converting α-iminonitriles into carboxamides have been developed. In combination with the oxidative three-component Strecker reaction, the one-pot direct amidation of aldehydes and alcohols is rep ...

Built-in 5-Aminooxazole as an Internal Activator of the Terminal Carboxylic Acid: An Alternative Access to Macrocyclodepsipeptides

Jieping Zhu

A conceptually novel macrolactonization technology is described. A strategically positioned 5-aminooxazole served as an internal traceless activator of the neighboring C-terminal carboxylic acid allowing the occurrence of macrolactonization under mild acid ...

Hydrogen storage and delivery: immobilization of a highly active homogeneous catalyst for the decomposition of formic acid to hydrogen and carbon dioxide

Paul Joseph Dyson, Gabor Laurenczy, Weijia Gan

The homogeneous catalytic system, based on water-soluble ruthenium(II)– TPPTS catalyst (TPPTS = meta-trisulfonated triphenylphosphine), selectively decomposes HCOOH into H2 and CO2 in aqueous solution. Although this reaction results in only two gas product ...

A DEMS study of methanol and formic acid oxidation on boron-doped diamond electrode

Christos Comninellis, Agnieszka Kapalka, György Foti

The electrochemical oxidation of methanol and formic acid in 1 M HClO4 is studied on boron-doped diamond electrode using differential electrochemical mass spectrometry (DEMS). DEMS is used to identify products and intermediates of the reaction monitored on ...

Activation of a terminal carboxylic acid by an internal oxazole: a novel synthesis of macrocyclodepsipeptide

Jieping Zhu

A new concept for the construction of macrocyclodepsipeptides from simple and readily available starting materials has been developed. The sequence consists of (a) a three-component reaction of an aldehyde, an amino alc., and a dipeptide isocyanate and (b) ...
