Desulfurization of isothiocyanates by a divalent germanium amide.

Ge[N(SiMe)] reacts with isocyanates but its reactivity with the related heavier congeners has not been explored. Its reaction with tertiary isothiocyanates results in the abstraction of the sulfur atom to yield a germanium(IV) dimer [((SiMe)N)GeS] in high yield. The reaction with -butylisoselenocyanate produced the related dimer [((SiMe)N)GeSe] within 5 minutes as shown using Se NMR spectroscopy.

Synthesis, Structure, Frontier Orbitals and Reactivity of PhGeN(SiMe): Rare Crystal Structure of a Germylamine.

The germylamine PhGeN(SiMe) was synthesized from PhGeCl and LiN(SiMe) and its X-ray crystal structure was determined. This structure represents only the fourth crystallographically characterized germylamine that has been reported. The two sterically encumbering -SiMe groups completely encapsulate the germanium-nitrogen bond and the geometry at the nitrogen atoms is trigonal planar rather than pyramidal.

The tale of two Ions Na and Cl: unraveling onion plant responses to varying salt treatments.

Background: Exploring the adaptive responses of onions (Allium cepa L.) to salinity reveals a critical challenge for this salt-sensitive crop. While previous studies have concentrated on the effects of sodium (Na), this research highlights the substantial yet less-explored impact of chloride (Cl) accumulation.

Unrevealing the Damage Fingerprint on Hazelnut Metabolome by Multiomic Platforms and AI-Aided Strategies.

The brown marmorated stink bug () poses a significant threat to hazelnut crops by affecting kernel development and causing quality defects, reducing the market value. While previous studies have identified bitter-tasting compounds in affected kernels, the impact of stink bug feeding on the hazelnut metabolome, particularly concerning aroma precursors, remains underexplored. This study aims to map the nonvolatile metabolome and volatilome of hazelnut samples obtained by caging on different cultivars in two locations to identify markers for diagnosing stink bug damage.

Development of an Untargeted Method for the Analysis of the Volatile Profile of Onions via Solid-Phase Microextraction Arrow-Headspace-Gas Chromatography-Mass Spectrometry Using Design of Experiments.

The distinctive aroma of onions, consisting primarily of sulfur-containing compounds, is one of the reasons for the popularity of the vegetable. The rapid enzymatic and chemical reactions that occur after the destruction of onion bulb tissue render the analysis of the volatile profile challenging. Therefore, sample preparation is a crucial step in the analysis of the onion volatilome, but it often does not receive the necessary attention in the literature.
