• General Description: Xylene, also known as dimethylbenzene, xylol, or mixed xylenes, is an aromatic hydrocarbon commonly found as a mixture of isomers (o-xylene, m-xylene, p-xylene) along with ethylbenzene. It is a colorless, flammable liquid with a sweet odor, widely used as a solvent in paints, coatings, and printing inks, as well as in the production of plastics and synthetic fibers. Due to its volatility, xylene can pose inhalation risks, and prolonged exposure may affect the nervous system, respiratory tract, and skin. Proper handling and ventilation are essential to mitigate health hazards.

BIOLOGICAL ACTIVITY OF 1-AROXYSILATRANES AND 1-AROXYSILATRAN-3-ONES

10.1007/BF00776329

The study investigates the biological activity of l-aroxysilatranes (la-c) and l-aroxysilatran-3-ones (lla, b). These compounds were synthesized through specific chemical reactions. The l-aroxysilatranes were produced by reacting tetraethoxysilane and triethanolamine with substituted phenols in xylene, while the l-aroxysilatran-3-ones were synthesized from N-bis(2-hydroxyethyl)aminoacetic acid and fluorophenyltrimethoxysilanes in a DMFA and benzene medium. The study focused on their potential roles in various biological processes, such as stabilizing erythrocyte membranes, inhibiting platelet aggregation, acting as anticoagulants, and stimulating the proliferative-repair function of connective tissue. The results indicated that compound Ia (l-(3-chlorophenoxy)silatrane) showed notable biological activity, including antihemolytic effects, inhibition of platelet aggregation, and positive effects on the biochemical indices of granulation-fibrous tissue, suggesting its potential therapeutic applications.

The study investigates the reactions of 2-diazoacenaphthenone (1) with various olefins and acetylenes. The researchers found that 1 did not decompose in boiling benzene or toluene but underwent copper-catalyzed thermolysis in boiling toluene to form biacenedione. In boiling xylene, 1 produced biacenedione and a trace amount of acenaphthenequinone ketazine. When 1 reacted with olefins like ethyl acrylate, acrylonitrile, ethyl a-bromoacrylate, and methyl vinyl ketone in refluxing benzene, it yielded spiro[acenaphthenone-2,1'-cyclopropanes] (3a-d, 4a-c, 7) with two stereoisomers for some reactions. Reactions with acrolein, phenylacetylene, and diethyl acetylenedicarboxylate led to the formation of 2'-hydroxymethylspiro[acenaphthenone-2,1'-cyclopropanes] (5, 6) and spiro[acenaphthenone-2,3'(3'H)-pyrazoles] (9, 10). The study also explored the reaction of 1 with bicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride, producing spiro[acenaphthenone-2,3'-tricyclooctanedicarboxylic anhydride] (8). The researchers used various analytical techniques to confirm the structures and properties of the synthesized compounds.
