Hemstroem, P. published the artcileIdentification and toxicological evaluation of cyclic sulfonium ion degradation products of sulphur mustard, Recommanded Product: 1,2-Bis(2-chloroethyl)disulfane, the publication is Marine Environmental Research (2020), 105047, database is CAplus and MEDLINE.

In the aftermath of WWII large amount seized German chem. munitions were dumped in the Baltic Sea by Allied forces. In this work, we have compared the chem. content of the solidified blocks of dumped WWII mustard gas collected from the Baltic Sea with solid precipitate from stored mustard gas, known as heel. We have identified the same cyclic sulfonium ions in both samples. In assessing the environmental and toxicol. impact of dumped sulfur mustard munitions on the worlds oceans the potential risk posed by cyclic sulfur mustard salts have so far not been incorporated. The toxicity of 1-(2-chloroethyl)-1,4-dithiane and its hydrolysis product 1-(2-hydroxyethyl)- 1,4-dithiane was evaluated using three different cell lines. Their effect on released pro-inflammatory cytokines was also measured. The toxicity tests showed low toxicity and low pro-inflammatory response and we therefore conclude that the environmental threat posed by these compounds is low.

Xu, Shiyan published the artcileReagent Control Enables Selective and Regiodivergent Opening of Unsymmetrical Phenonium Ions, Synthetic Route of 620-20-2, the publication is Journal of the American Chemical Society (2020), 142(18), 8090-8096, database is CAplus and MEDLINE.

The first examples of selective and regiodivergent chlorination of unsym. benzyl-substituted epoxides, I [R = 4-methoxyphenyl, Ph, 2H-1,3-benzodioxol-5-yl, 1-[(4-methylbenzene)sulfonyl]-2,3-dihydro-1H-indol-5-yl, etc.; R¹ = Pr, 4-methoxyphenyl, 4-cyanobutyl, 4-(benzyloxy)butyl, etc.] have been reported. These reactions are enabled by the dual role of SnCl₄ and TiCl₄ as Lewis acids and chloride nucleophiles. Reagent control dictates addition of chloride at either the substituted internal position (SnCl₄) or unsubstituted terminal position (TiCl₄) of the phenonium ion. These reactions are highly selective, stereospecific, and operationally simple, and proceed in good to excellent yields. Diverse product utility is demonstrated.

Hess, U. published the artcileSynthesis of 4-aryl-1λ²,2λ⁴-dithia-3,4-diaza-buta-1,2-dienes, a new dithiadiazabutadiene system, Application of 4-Amino-2,6-dichlorobenzoic acid, the publication is Pharmazie (1994), 49(2-3), 121-5, database is CAplus and MEDLINE.

4-Aryl-1λ²,2λ⁴-dithia-3,4-diaza-buta-1,2-dienes, e.g. 2-O₂NC₆H₄NHN:S:S, as representatives of a dithiadiazabutadiene structure in which sulfur occupies a different oxidation number are synthesized by reaction of diazotated acceptor-substituted aryl- and hetarylamines with thiosulfates or disodium disulfide in strong acid solution For some examples a first pharmacol. test indicate an immune-stimulating effect. Anal. examination as well as as MNDO calculation which give some mechanistical insight, supplements the new synthesis.

Saito, Tetsuo published the artcileSystemic inseccticidal properties of certain organic phosphorus compounds to the green peach aphid, Myzus persicae, and the tobacco cutworm, Prodenia litura, Name: Diethyltrichloromethylphosphonate, the publication is Bochu Kagaku (1966), 31(2), 77-81, database is CAplus.

Screening tests of insecticidal activity for ∼50 organophosphorus compounds used the sucking insect, green peach aphid, and the chewing insect, tobacco cutworm. The established systemic insecticides were usually highly toxic to the aphid while being less toxic to the cutworm. One of the thiophosphate esters, ((EtO)2P(S)SCH2CO2(CH2)2Cl) was toxic to the cutworm. Five phosphate esters were toxic to both insects. O,O-Di-Me dichlorohydroxyethanephosphonate and its Ac ester, O,O-di-Me trichlorohydroxyethanephosphonate and its Et Me homolog were more toxic to the cutworm than the aphid. The test plant was cabbage and the test chems. were formulated with Me2CO-C6H6-emulsifier 30:30:30% weight/weight Insecticidal activity was indicated by mortality at concentrations of 1000 ppm. or lower.

Gevorgyan, Ashot published the artcileFormal C-H Carboxylation of Unactivated Arenes, SDS of cas: 637-07-0, the publication is Chemistry – A European Journal (2020), 26(27), 6064-6069, database is CAplus and MEDLINE.

A formal C-H carboxylation of unactivated arenes e.g., I using CO₂ in green solvents is described. The present strategy combines a sterically controlled Ir-catalyzed C-H borylation followed by a Cu-catalyzed carboxylation of the in situ generated organoboronates. The reaction is highly regioselective for the C-H carboxylation of unactivated arenes e.g., I (1,3-disubstituted and 1,2,3-trisubstituted benzenes, 1,2- or 1,4-sym. substituted benzenes, fluorinated benzenes and different heterocycles). The developed methodol. was applied to the late-stage C-H carboxylation of com. drugs and ligands.
