Up to five different crystalline radical salts have been prepared with the organic donor BEDT-TTF and three different polynitrile anions. With the polynitrile dianion tcpd 2− (=C[C(CN)2]3 2− ), two closely related radical salts: α'-(ET)4tcpd·THF (1) (THF = tetrahydrofurane) and α'-(ET)4tcpd·H2O (2) have been prepared, depending on the solvent used in the synthesis. With the mono-anion tcnoetOH ...

A new ylide-based protocol for the asymmetric aziridination of imines via methylene transfer has been developed involving the use of a simple chiral sulfonium salt and an organic strong base. A systematic study identified triisopropylphenyl sulfonylimines as optimal substrates for the process. Unexpectedly, hindered C2-symmetric sulfonyl salts incorporating bulky ethers at C-2 and C-5--which ha...

Organic phosphonium salts have served as important intermediates in synthetic chemistry. But the use of a substituent on the positive phosphorus as a nucleophile to construct C-C bond remains a significant challenge. Here we report an efficient transition-metal-free protocol for the direct nucleophilic arylation of carbonyls and imines with tetraarylphosphonium salts in the presence of caesium ...

natural organic wastes contain considerable amounts of nutritional elements. the availability and uptake of nutrient elements in soil) especially in alkali and calcareous soils) increase due to high content of organic matter, and reduce the micro-elements deficiencies. organic wastes have pathogenic contaminations that come from waste type and transmitted by microorganisms such as bacteria, fun...

Structural aspects of the Bechgaard salts (TMTSF)2X and related 2:1 salts. mostly based on the sulfur donors TMTTF and BCPOITF as well as on the hybrid TMDTDSF dorlor, are considered in relationship with their physical properties. The basic structure of these softs is revie~ved with a special emphasize on the dimerization of the organic stack and on the disorder of the aurons IX). 0lhen the den...

(2) the low-ash tendency of the west coast sugars is due to low concentrations of both inorganic and organic salts, and (3) the moderately high ash of the eastern sugars is due to high concentrations of organic salts and in spile of low values for inorganic salts. In addition, from portions of the tables presented earlier, we may say tha t the differences in the salt components of the sugars ar...

1-alkyl-3-methyl-imidazolium (Cn-mim) salts are examples of ionic liquids (ILs).[1] In these salts, the cation is a bulky organic molecule: accordingly, due to factors such as the hindered ion packing and low charge density, the melting point is relatively low compared with conventional inorganic salts. As a consequence, it is possible to synthesise ILs which are liquid at room temperature. The...

The practice of composting mixed green wastes from community collection programs has been on the increase as a means to reduce organic debris to landfills. Recent reports of plant injury have appeared and were attributed to residues of the herbicide clopyralid in compost. Phytotoxicity issues with compost have been reported previously to result from other factors, including heavy metal content,...

In a previous work we have demonstrated the antimicrobial activity of ferrocenyl or phenyl derivatives of diphenyl butene series. This finding has opened a new area of applications of organometallic compounds. In order to improve these activities, we have synthesized new organic and organometallic diaryl butene compounds with different lengths of their amino chains. These new compounds, and als...
