Moderhack, Dietrich published the artcilePhenylcarbamoylation of N-acetyl-1,2,4-triazolium-4-aminides revisited, Recommanded Product: 4-Amino-1-methyl-4H-1,2,4-triazol-1-ium iodide, the main research area is phenylcarbamoylation acetyltriazolium aminide.

The reaction of N-acetyl-1,2,4-triazolium-4-aminides with PhSCN affords ring functionalized products rather than linear adducts. Analogous compounds are obtained from 1-acetamido-4-methyl-4H-1,2,4-triazolium iodide and its imidazolium congener. Twofold carbamoylation occurs on reaction of aminotriazolium salts in the presence of base. Azoliums having Me at C(5)/(2) are inert throughout.

Laus, Gerhard published the artcileSynthesis and crystal structures of new 1,4-disubstituted 1,2,4-triazoline-5-thiones, Recommanded Product: 4-Amino-1-methyl-4H-1,2,4-triazol-1-ium iodide, the main research area is triazolinothione preparation crystal structure.

The simple synthesis of sulfur into the 5-position of 1,4-disubstituted quaternary 1,2,4-triazolium salts by two methods was investigated. The syntheses of 1,4-disubstituted 1,2,4-triazoline-5-thiones I (R1 = CH3, NH2, N(CH3)2, OCH2C6H5; R2 = CH3, CH(CH3)2, NH2, etc.) were reported. Thermolysis of I (R1 = R2 = CH3) in air gave 1,4-dimethyl-1,2,4-triazolium hydrogen sulfate. Crystal structures of I were determined by single-crystal X-ray diffraction. Intermol. hydrogen bonds (C-H-S, C-H-N, N-H-N, N-H-S) were observed in the solid state. The solvent-dependent 1H NMR chem. shifts of signals satisfactorily correlated with the Kamlet-Abboud-Taft π* and β parameters in ten solvents. From the lack of correlation with the α parameter and from the C:S bond length (average 1.67°), a significant contribution of a mesoionic imidazolium-2-thiolate resonance structure seems unlikely.

Ammonium, 1,5-diamino-4-methyl-tetrazolium and 4-amino-1-methyl-triazolium salts of 5-difluoroaminodifluoromethyl-tetrazolate (TA-CF2NF2) were prepared by metathesis reactions of silver 5-difluoroaminodifluoromethyl-tetrazolate and the corresponding iodides. All are thermally stable to ∼150°. The ammonium salt has a d. of 1.88 g/cm-3. The combination of the CBS-4 method and isodesmic bond separation reactions was an economical and reliable method to estimate heats of formation for polyfluorinated mols. The standard heats of formation (ΔfH0298) of ammonium 5-difluoroaminodifluoromethyl-tetrazolate was calculated to be -53.13 kcal/mol-1 using the CBS-4 method. While its detonation pressures (P) and velocities (D) were estimated using Cheetah 4.0: P = 28.78 GPa; D = 8490 m/s-1; detonation properties for 1,5-diamino-4-methyl-tetrazolium salts of 5-difluoroaminomethyltetrazolate (TA-CH2NF2), 5-difluoroaminotetrazolate (TA-NF2) and 5-difluoroaminodinitromethyl-tetrazolate (TA-C(NO2)2NF2) are also compared based on predicted densities and computed heats of formation.

Boron nanoparticles prepared by milling in the presence of a hypergolic energetic ionic liquid (EIL) are suspendable in the EIL and the EIL retains hypergolicity leading to the ignition of the boron. This approach allows for incorporation of a variety of nanoscale additives to improve EIL properties, such as energetic d. and heat of combustion, while providing stability and safe handling of the nanomaterials.

Phelan, James P. published the artcileRapid access to diverse, trifluoromethyl-substituted alkenes using complementary strategies, Product Details of C7H6BrN3, the main research area is trifluoromethyl alkene preparation; silyl alc trifluoromethyl cross coupling palladium; Peterson elimination; organotrifluoroborate cross coupling palladium.

Two synergistic approaches to the facile assembly of complex α-trifluoromethyl alkenes are described. Using α-trifluoromethyl-β-silyl alcs. as masked trifluoromethyl alkenes, cross-coupling or related functionalization processes at distal electrophilic sites can be executed without inducing Peterson elimination. Subsequent Lewis acidic activation affords functionalized α-trifluoromethyl alkenes. Likewise, the development of a novel α-trifluoromethylvinyl trifluoroborate reagent complements this approach and allows a one-step cross-coupling of (hetero)aryl halides to access a broad array of complex α-trifluoromethyl alkenes.
