Myeloperoxidase (MPO) structural analysis has suggested that halides and pseudohalides bind to the distal binding site and serve as substrates or inhibitors, while others have concluded that there are two separate sites. Here, evidence for two distinct binding sites for halides comes from the bell-shaped effects observed when the second-order rate constant of nitric oxide (NO) binding to MPO wa...

The hetero-anionic lead-free double perovskite halides are realized through mechanochemical synthesis by Tae Heon Kim and co-workers in article number 2201119. degree of anion substitution is tunable inducing manipulation the band gaps emitted colors anionic-mixed halides. gap engineering via exchange applicable to fabricate optoelectronic devices with high performance.

The mechanism of reductive cleavage of model alkyl halides (methyl 2-bromoisobutyrate, methyl 2-bromopropionate, and 1-bromo-1-chloroethane), used as initiators in living radical polymerization (LRP), has been investigated in acetonitrile using both experimental and computational methods. Both theoretical and experimental investigations have revealed that dissociative electron transfer to these...

the conversion of the cellulose into 5-hmf would experience three steps, cellulose to glycose, glycose to fructose and fructose to 5-hmf. chloride ion can break down the hydrogen bond in cellucose, chromium can catalyze the isomerization of glycose to fructose, and the high temperature is helpful to cyclohydration of fructose to 5-hmf. in this paper, the sawdust has been directly degraded into ...

Scintillator materials convert high-energy radiation into photons in the ultraviolet to visible light region for detection. In this review, advances X-ray emission dynamics of inorganic scintillators are presented, including halides (alkali-metal halides, alkaline-earth rare-earth oxy-halides, oxyorthosilicates, halide perovskites), oxides (binary oxides, complex post-transition metal oxides), ...

The regioselectivity on a cyclic thioamide group towards different electrophiles was studied on the model compound 4-methyl-1-thioxo-1,2,4,5-tetrahydro[1,2,4]triazolo [4,3-a]quinazolin-5-one 1. The examined compound 1 reacts with alkyl halides, amines in the presence of formaldehyde, acyl halides and compounds having activated double bonds to afford the N-substituted derivatives 2, 3 and 6. The...

An iron-catalyzed diboration reaction of alkynes with bis(pinacolato)diboron (B2pin2) and external borating agents (MeOB(OR)2) affords diverse symmetrical or unsymmetrical cis-1,2-diborylalkenes. The simple protocol for the diboration reaction can be extended to the iron-catalyzed carboboration of alkynes with primary and, unprecedentedly, secondary alkyl halides, affording various tetrasubstit...
