چکیده
Abstract: 3-(Trifluoromethyl)prop-2-yne 1-iminium triflate salts were generated from 3-trifloxy-3-(trifluoromethyl)prop-2-ene by triethylamine-assisted elimination of triflic acid and trapped in situ various cycloaddition reactions. These included Diels-Alder reactions with 1,3-dienes, [2+2] 1,4-diphenylbuta-1,3-diene, [3+2] organoazides. All these revealed the excellent dienophilic dipolarophilic reactivity electrophilic C,C triple bond novel 3-CF3-propyniminium salts.

Hydrolyzing metal salts as coagulants*
Aluminium and ferric salts are widely used as coagulants in water and wastewater treatment. They are effective in removing a broad range of impurities from water, including colloidal particles and dissolved organic substances. Their mode of action is broadly understood in terms of essentially two mechanisms: charge neutralization of negatively charged colloids by cationic hydrolysis products an...

The synthesis and characterisation of a series of new gold- and palladium-containing symmetrical imidazolium salts are described which display significant cation-dependent effects determined by the structure of the alkyl chains of the imidazolium motifs. Whereas direct reduction of the Pd salts can produce stable nanoparticles (NPs) coated by imidazolium salts, the addition of strong base to th...

متن کاملGemini alkylammonium salts as biodeterioration inhibitors.
To protect materials against biodeterioration, physical, biological or chemical methods can be used. Chemical inhibitors of biodeterioration are the most common and effective. A new class of chemical inhibitors-gemini alkylammonium salts-shows excellent biocidal properties and good ecological profile. These compounds can be applied as biodeterioration inhibitors in a wide variety of materials.
