Phase-vanishing halolactonization of neat substrates
Beilstein Journal of Organic Chemistry, 2008 Phase-vanishing reactions are triphasic reactions which involve a reagent, a liquid perfluoroalkane as a phase screen and a substrate. The perfluoroalkane does not dissolve any of the reactants and is used to separate them.

rac-(E,trans)-4-Bromo-10,10-dimethyl-9,11-dioxabicyclo[6.3.0]undec-4-ene
IUCrData, 2020 In the title compound, a cyclooctene ring in a twist-boat conformation and a dioxolane ring with a distorted envelope conformation are annulated in a trans configuration. Alternating strands of single enantiomers build up the crystal. Within the strands,

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Bromine mass balance calculation for dairy cows fed bromoform-based feed additives
Journal of Agriculture and Food ResearchBromoform-based feed additives exhibit strong antimethanogenic potential. It is hypothesized that bromoform is dehalogenated in the rumen into multiple end products, including methane and bromine, yet little is known about bromine distribution and ...

Regioselective Synthesis of 5-Propyl-2-((trityloxy)methyl)thiophene-3-carbaldehyde
Molbank, 2021 5-propyl-2-((trityloxy)methyl)thiophene-3-carbaldehyde was synthesized by using the concept of chemo- and regioselective Br/Li exchange reaction from 3-bromo-5-propyl-2-((trityloxy)methyl)thiophene.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Modelling future changes to the stratospheric source gas injection of biogenic bromocarbons
Geophysical Research Letters, 2012 Simulations with a chemistry‐climate model (CCM) show a future increase in the stratospheric source gas injection (SGI) of biogenic very short‐lived substances (VSLS).

Advanced Functional Materials, EarlyView.Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.
