The intramolecular asymmetric cyclization of aldehydes has been accomplished using singly occupied molecular orbital (SOMO) catalysis. Selective oxidation of chiral enamines (formed by the condensation of an aldehyde and a secondary amine catalyst) leads to the formation of a 3π-electron radical species. These chiral SOMO-activated radical cations undergo enantioselective cyclization with an ar...

Soil organic matter can be divided into stable and labile, with the latter directly supporting plant growth development during growing season. To restore soil fertility ensure high productivity of agrocenoses, a certain ratio between labile parts humus must maintained. The purpose this study was to determine content under different tillage fertilisation options establish optimal their total car...

Aim. To study the effect of long-term use primary soil treatment and fertilization systems on yield white mustard. The results research impact basic fertilizer economic efficiency mustard production in Forest-Steppe zone Ukraine are presented order to identify most effective, adapted natural climatic conditions recent years. Methods. was conducted during 2018–2021 a stationary two-factor field ...

Understanding the processes underlying carbon (C) stability in soils is of utmost importance context climate change. In this setting, biochar often studied for its persistence and reported to have positive impacts on soil fertility. Whilst recent research has mostly focused short-term effects amendments soil, a better understanding long-term needed. Our study focuses agricultural enriched charc...

It is a great pleasure to be able to introduce this Themed series on organo-fluorine chemistry in the Beilstein Journal of Organic Chemistry. The introduction of fluorine into organic molecules is widely practiced particularly when tuning the properties of molecules for specialist functions. Of particular prominence is the role fluorine substitution finds in pharmaceutical development [1], and ...

New barley products can be developed by modifying the content of bioactive components in grain through breeding, as well improving its quality at lower fertilizer costs. We aimed to study effects genotype, growth conditions, and top-dressing application nitrogen organo-mineral fertilizers on chemical composition grain.
 The varieties Novichok, Rodnik Prikamya, Pamyaty Rodinoy were grown un...

Interactions between organic and detrital mineral phases strongly influence both the dispersal accumulation of terrestrial carbon (OC) in continental margin sediments. Yet complex interplay among biological, chemical, physical processes limits our understanding how organo-mineral interactions evolve during sediment transfer burial. In particular, diverse OC sources hydrodynamic hinder assessmen...
