Ultra-fast catalytic detoxification of organophosphates by nano-zeolitic imidazolate frameworks

Detrimental and injurious impacts of Organophosphates that have had on environment, humans, organisms and the other animals or plants have not been surreptitious to anyone worldwide. Nevertheless, up to now, among many efforts that have been devoted to detoxification of Organophosphates (OPs), catalytic detoxification has been the most applicable, cost-effective, efficacious and safest way to break down these dangerous materials. Herein, the utilization of zeolitic imidazolate frameworks (ZIFs), for the first time, has been reported to deactivate Diazinon as an organophosphate agent demonstrated at room temperature. In the following research, the catalysts were analyzed by PXRD, FT-IR, FE-SEM, BET, CO2 adsorption/desorption and TG. The decontamination processes were followed by 31P NMR, HPLC, and UV–vis to evaluate catalytic efficiency. Interestingly, supreme reusability, durability and potentially stunning catalytic activity represent them as alternate materials for their amazing elimination of OPs compared to the other MOFs.

Silica-Bound Sulfonic Acid Catalysts

The catalytic activity of colloidal silica sulfonic acid for the hydrolyses of diazinon and triphenylmethyl fluoride was compared with that of silica gel sulfonic acids, gel and macroporous poly(styrenesulfonic acids), powdered and soluble Nafion, p-toluenesulfonic acid, and hydrochloric acid.For diazinon hydrolysis, the colloidal catalyst was only slighty less active than the soluble strong acid catalysts and 2.8 times more active than any of other heterogeneous catalysts.The silica gel and polymeric sulfonic acid catalysts had similar activities.For triphenylmethyl fluoride hydrolysis all of the catalysts were only weakly active.

Bifunctional Thiourea-Catalyzed Stereoablative Retro-Sulfa-Michael Reaction: Concise and Diastereoselective Access to Chiral 2,4-Diarylthietanes

Owing to the chiral recognition capacity of bifunctional thioureas, a stereoablative retro-sulfa-Michael reaction has been developed. Utilization of a biphasic system enabled us to render the process catalytic. The usefulness of this methodology was further illustrated by the diastereoselective synthesis of all possible stereoisomers of 2,4-diarylthiethanes.

Dual nucleophilic substitution reactions of O,O-diethyl 2,4-dinitrophenyl phosphate and thionophosphate triesters

The reactions of the title compounds with phenoxides, secondary alicyclic (SA) amines, and pyridines, in 44 wt% ethanol-water, at 25°C and an ionic strength of 0.2 M, were subjected to kinetic and product studies. From analytical techniques (HPLC and NMR), two pathways were detected (nucleophilic attack at the phosphoryl center and at the C-1 aromatic carbon) for the reactions of all the nucleophiles with the phosphate (2) and for the pyridinolysis of the thionophosphate (1). Only aromatic nucleophilic substitution was found for the reactions of 1 with phenoxides and SA amines. For the dual reactions, the nucleophilic rate constants (kN) were separated in two terms: documentclass{article}usepackage{amssymb} pagestyle{empty}begin{document}k-{rm N}^{rm P}end{document} and documentclass{article}usepackage{amssymb}pagestyle{empty}begin{document}k-{ rm N}^{{rm Ar}}end{document}, which are the rate constants for the corresponding electrophilic centers. The absence of a break in the Bronsted-type plots for the attack at P is consistent with concerted mechanisms. The Bronsted slopes, βAr 0.32-0.71, for the attack at the aromatic C-1, are in agreement with stepwise mechanisms where formation of a Meisenheimer complex is the rate-determining step. 2013 Wiley Periodicals, Inc.
