2'-Dithiobis(benzothiazole) is used as a fungicide, insecticide, sensitizer and anti-scorching agent in vulcanization of rubber.5 2-Mercaptobenzimidazole (MBI) is an important chemical for many industrial applications, such as an inhibitor for copper plating, antioxidant for plating rubber compounds, adsorbent for heavy metal, antiseptic and medical substances.6-8 MBI is used as a non-staining secondary antioxidant
A series of benzo [d] [1,3] azoles 2-substituted with benzyl- and allyl-sulfanyl groups were synthesized, and their cytotoxic activities were in vitro evaluated against a panel of six human cancer cell lines. The results showed that compounds BTA-1 and BMZ-2 have the best inhibitory effects, compound BMZ-2 being comparable in some cases with the reference drug tamoxifen and exhibiting a low cytotoxic

(EN) An aroyl halide is brominated in the liquid phase with bromine and with a Lewis acid catalyst. If the reaction mixture comprises excess bromine along with m-bromoaroyl halide, substantially all of the excess bromine is removed from the mixture. The m-bromoaroyl halide mixing and reacting with a substituted or unsubstituted aromatic compound to produce a reaction mixture comprising a substituted diaryl ketone in which the substitution comprises a bromine atom in the meta position of one of its rings directly bonded to the carbonyl group. Preferably, the substituted diaryl ketone is reacted with a vinylic olefin in a palladium-catalyzed arylation of the olefin to form a substituted diaryl ketone in which the substitution comprises an olefinic substituent in the meta position of one of its rings formerly occupied by a bromine atom. This product can then be reacted with carbon monoxide in a palladium-catalyzed hydrocarboxylation or hydrocarbalkoxylation reaction. The process enables the efficient large scale production of carboxylic acids, or derivatives thereof, such as 2-(3-benzoylphenyl)propionic acid (also known as ketoprofen), a well known commercially successful anti-inflammatory and analgesic agent.(FR) On brome un halogénure d'aroyle en phase liquide avec du brome et un catalyseur à l'acide de Lewis. Si le mélange réactionnel contient trop de brome dans l'halogénure de m-bromoaryle on enlève sensiblement tout le surplus de brome du mélange. On mélange et on fait réagir l'halogénure de bromoaryle avec un composé aromatique substitué ou non substituée pour produire un mélange réactionnel comprenant une cétone de diaryle substituée dans laquelle la substitution comprend un atome de brome en position méta d'un de ses anneaux directement lié au groupe carbonyle. On fait de préférence réagir la cétone de diaryle substituée avec une oléfine vinylique dans un processus d'arylation de l'oléfine catalysé au palladium pour former une cétone de diaryle substituée dans laquelle la substitution comprend un substituant oléfinique dans la position méta d'un de ses anneaux occupée auparavant par un atome de brome. On peut ensuite faire réagir ce produit avec du monoxyde de carbone dans une réaction d'hydrocarboxylation ou d'hydrocarbalcoxylation catalysé au palladium. Ce procédé permet de produire efficacement et à grand rendement des acides carboxyliques ou des dérivés de ces derniers tels que l'acide 2-(3-benzoylphényl) acide propionique (également connu sous le nom de kétoprofène) qui est un agent analgésique et anti-inflammatoire très connu dont la vente est un succès commercial.
