The structure of the title compound, CHN, at 93 K has monoclinic (2/) symmetry. The title compound was prepared by treatment of 2-(2,6-diiso-propyl-phenyl)-3,3-dimethyl-2-aza-spiro-[4.5]dec-1-en-2-ium hydrogen dichloride with two equivalents of lithium di-ethyl-amide. Characterization of the title compound by single-crystal X-ray diffraction and H and C NMR spectroscopy is presented. Formation of the di-ethyl-amine adduct of the cyclic(alk-yl)(amino)-carbene (CAAC) was unexpected, as deprotonation using lithium diiso-propyl-amide results in free CAAC formation.

Gray mold disease is caused by B. cinerea, which could severely reduce the production yield and quality of tomatoes. To explore more potential fungicides with new scaffolds for controlling the gray mold disease, ten aldehydes-thiourea derivatives were designed, synthesized and assayed for inhibitory activity against three plant pathogenic fungi.

Limited literature addresses the association between pollution, stress, and obesity, and knowledge synthesis on the associations between these three topics has yet to be made. Two reviewers independently conducted a systematic review of MEDLINE, Embase, and Web of Science Core Collection databases to identify studies dealing with the effects of semi-volatile organic compounds, pesticides, conservatives, and heavy metals on the psychosocial stress response and adiposity in humans, animals, and cells. The quality of papers and risk assessment were evaluated with ToxRTool, BEES-C instrument score, SYRCLE's risk of bias tool, and CAMARADES checklist.

Unlabelled: Mesenchymal‒epithelial transition factor (c-Met), a receptortyrosine kinase (RTK), plays a vital role in cell proliferation, migration and invasion, and tumour metastasis.
Objective: With increasing duration of treatment, many tumours gradually develop drug resistance. Therefore, novel antitumour drugs need to be developed to treat patients with tumours.

Three new sodium manganese fluoro-pyrophosphate compounds, namely, NaMn(PO)F (I), NaMn(PO)F (II), and NaMn(PO)F (III), have been synthesized by heating a mixture of NaPF, NaPOF or NaHPO with different Mn sources in NaNO and KNO fluxes. The structures of the title compounds were characterized single-crystal X-ray diffraction (XRD). II is characteristic of a shell of Na ions that encloses one [Mn(PO)F] unit, whereas I and III reveal three-dimensional (3D) frameworks that consist of MnO, Mn/NaOF octahedra or MnO octahedra and distorted MnO square pyramids with PO units, where Na cations reside in different-membered ring one-dimensional (1D) tunnels.
