Polyurethane (PU) superfine fiber leathers have been widely used in people's life. However, the flammability brings potential risks to their application. Therefore, more and more attention has been paid to the flame retardant modification of PU leathers. In the 1980s, researchers found that some brominated flame retardants produced dioxins during combustion. In 2007, the EU began implementing the REACH regulation, which restricted the use of certain halogenated flame retardants, so a majority of studies focused on halogen-free flame retardant modification. In addition, the halogen-free flame r

Abstract:
5-Iodo-1-arylpyrazoles are interesting templates for investigating the halogen bond propensity in small molecules other than the already well-known halogenated molecules such as tetrafluorodiiodobenzene. Herein, we present six compounds with different substitution on the aryl ring attached at position 1 of the pyrazoles and investigate them in the solid state in order to elucidate the halogen bonding significance to the crystallographic landscape of such molecules. The substituents on the aryl ring are generally combinations of halogen atoms (Br, Cl) and various alkyl groups. Observed halogen

Accurate determination of carbon core-electron binding energies (C1s CEBEs) is crucial for X-ray photoelectron spectroscopy (XPS) assignments and predictive computational modeling. This study evaluates density functional theory (DFT)-based methods for calculating C1s core-electron binding energies (CEBEs), comparing three functionals—PW86x-PW91c (DFTpw), mPW1PW, and PBE50—across 68 C1s cases in small hydrocarbons and halogenated molecules (alkyl halides), using the delta self-consistent field ΔSCF (or ΔDFT) method developed by Chong et al. over the past decade.

β-Pinene can be used as a cheap source to synthesize a large number of high value-added derivatives. In this study, a series of β-pinene derivatives was prepared, and the antifungal activities of the compounds were assessed against phytopathogenic fungi. Eight N-alkyl hydronopyl diethyl ammonium halide salts were synthesized by the reaction of hydronopyl diethyl ammonium halide with 8 halogenated alkanes. The structures of the synthesized products were characterized by Fourier-transform infrared spectroscopy and nuclear magnetic resonance spectroscopy and mass spectrometry. The antifungal acti

Bis(stannyl)silanes of types R3Sn-SiR′2-SnR3 and R2(H)Sn-SiR′2-Sn(H)R2 with R′ being methyl, phenyl, iso-propyl or terf-butyl have been synthesized by treatment of difunctionalized diorganosilanes with alkali stannides (R = Me, tBu; R′= Me, iPr; 1 - 6, 8 ) or with triphenyltin chloride and magnesium (R = Ph; R′ = Me, iPh;Pr; 7, 9). Me3Sn-SitBu2-SnMe3 4, was halogenated using SnCl4, to yield the bis(chlorostannyl)silane 11. The reaction of bis(stannyl)diorganosilanes R3SnSiR′SnR3 with catalytic amounts of Pd(PPh3)4 resulted in unexpected rearrangements under formation of the silyldistannanes R3
