[Bis(Trimethylsilyl)Methyl]Lithium and -Sodium: Solubility in Alkanes and Complexes with O- and N- Donor Ligands

Inorganics, 2017
In contrast to alkyl compounds of lithium, which play an important role in organometallic chemistry, the corresponding heavier alkali metal compounds are less investigated.

Gram‐Scale Photocatalysis with a Stable and Recyclable Chromium(III) Photocatalyst in Acetonitrile and in Water

Advanced Synthesis &Catalysis, EarlyView.
Abstract The use of stable photosensitizers made on a multigram‐scale from cheap and available starting materials offers an extraordinary opportunity to translate small‐scale proof‐of‐concept photoreactions to widespread applications in non‐specialized laboratories, thereby promoting the implementation of light‐driven syntheses.

Analysis of serum metabolism in premature infants before and after feeding using GC–MS and the relationship with necrotizing enterocolitis

Biomedical Chromatography, Volume 37, Issue 1, January 2023., 2023
Abstract Preterm birth and enteral feeding are two main factors leading to necrotizing enterocolitis (NEC). The metabolomics of preterm infants before and after feeding can provide a basis for the prediction of NEC. Using the method of cross‐sectional study, the mode was established with the serum samples of 19 premature infants at birth and after ...

Potassium chloridotris(hypersiloxy)aluminate dimer

Acta Crystallographica Section E: Crystallographic Communications, 2019
The tris(trimethylsilylsiloxide) ligand, also known as hypersiloxide, is an extremely bulky group. In an attempt to make the monomeric Al(OSi(SiMe3)3)3, AlCl3 was combined with 3 equiv. of potassium hypersiloxide.

Chemical Variability of Hexane Extracts from Five Subspecies of Calendula suffruticosa from Spain

Chemistry &Biodiversity, Volume 19, Issue 12, December 2022., 2022
Abstract The chemical profile of the hexane extracts of the subspecies carbonellii, greuteri, marginata, trialata, and vejerensis of Calendula suffruticosa growing in Spain, herein described for the first time, were studied to access their value as a chemo taxonomical tool and search for potentially useful compounds. The subsp. greuteri and carbonellii

π‐Extended Heli(aminoborane)s with Highly Bright Circularly Polarized Luminescence and Narrowband Emission

Angewandte Chemie, EarlyView.
Three π‐extended heli(aminoborane)s (E[10]HAB‐A/B/C) were synthesized to find a balance between fluorescence quantum yield (Φlum) and absorption/luminescence dissymmetry factors (gabs/glum). These molecules exhibited remarkable photophysical properties, including high Φlum and narrowband emission (full width at half maximum, FWHM=16 nm), in which E[10 ...
