Silica sulfuric acid: a versatile and reusable heterogeneous catalyst for the synthesis of N-acyl carbamates and oxazolidinones under solvent-free conditions

Bulletin of the Chemical Society of Ethiopia, 2011
Silica sulfuric acid catalyzes efficiently the reaction of carbamates and oxazolidinones with anhydrides under solvent-free conditions. All the reactions were done at room temperature and the N-acyl carbamates and oxazolidinones were obtained with high ...

Ultra‐High Strength and Environmentally Stable Fluorinated Solid‐State Ion‐Conductive Elastomers with Folding‐Paper‐Structured Triboelectric Nanogenerators for Wave Energy Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a polyurethane‐based fluorinated SICEs with excellent mechanical properties (7.35 MPa and 61.4 MJ m−3), conductivity (4.2 × 10−4 S cm−1), and harsh environmental resistance were prepared by a “three birds with one stone” strategy that combines multiple interactions with fluorine effects. The paper‐folding TENG is capable of harvesting not

Classification, Chemical, and Toxicological Properties of Carbamate Nerve Agents

Journal of Xenobiotics
Nerve agents are usually identified as exceedingly toxic organophosphate compounds like VX and sarin. Nevertheless, although carbamate nerve agents (CNAs) have been developed they constitute the least studied class of nerve agents outside military ...

Photochemical Amination of Thioethers Under Biphasic Flow Conditions

European Journal of Organic Chemistry, EarlyView.
Biphasic reaction conditions for the iron‐catalyzed synthesis of sulfilimines and sulfoximines in continuous flow using 2,2,2‐trichloroethyl‐N‐mesyloxycarbamate (TrocNHOMs). A practical, continuous flow, biphasic photochemical amination of thioethers, employing N‐mesyloxycarbamates as nitrene precursors, is reported. Using UVA irradiation at 365 nm and

The In Vitro Transgenic Rodent Assay in Primary MutaMouse Hepatocytes Compared to the Mammalian Cell Gene Mutation Assay Using the HPRT Gene

Environmental and Molecular Mutagenesis, EarlyView.
ABSTRACT Gene mutations can be detected in mammalian cells in vitro using indicator genes such as the hypoxanthine‐guanine‐phosphoribosyltransferase (HPRT) gene. These assays have been adopted as OECD test guidelines (TG, e.g., OECD TG no. 476) and are used for regulatory purposes.
