Usage

Uses

6-Methylchrysene is one of the methylated chrysenes (MeChry), as an aryl hydrocarbon receptor (AhR) agonist. Methylated chrysenes (MeChry) are important cigarette smoke constituents and 6-MeChry has b een listed as possibly carcinogenic to humans.

Palladium-Catalyzed Sequential Vinyl C–H Activation/Dual Decarboxylation: Regioselective Synthesis of Phenanthrenes and Cyclohepta[1,2,3-de]naphthalenes

The application of a C(vinyl), C(aryl)-palladacycle from vinyl-containing substrates is challenging due to the interference of a reactive double bond in palladium catalysis. This Letter describes a [4 + 2] or [4 + 3] cyclization based on a C(vinyl), C(aryl)-palladacycle by employing α-oxocarboxylic acids as the insertion units under a palladium/air system. The reaction proceeded through the key vinyl C–H activation and dual decarboxylation sequence, forming phenanthrenes and cyclohepta[1,2,3-de]naphthalenes regioselectively in good yields. The synthetic versatility of this protocol is highlighted by the gram-scale synthesis and synthesizing functional material molecule.

Characterization of the combustion products of polyethylene

Polyethylene (PE) was burned in a tube-type furnace with an air flow at a temperature of 600~900°C. Combustion products were collected with glass wool, glass fiber filter, and XAD-2 adsorbent. The analysis of the products was performed with GC-FID and GC-MSD. At low temperature, hydrocarbons were the major components, while at higher temperature the products were composed of polycyclic aromatic hydrocarbons. With the high performance of the Hewlett-Packard 6890GC-5973MSD, more compounds were identified in comparison with previous studies.

Acid-catalyzed rearrangement of cyclobutanols. Syntheses of chrysenes, cyclopentenophenanthrenes, and diarylmethanes

Acid-catalyzed reactions of 8-aryl or 8,8-diarylbicyclooct-2-en-7-ols lead to tetrahydrophenanthrene derivatives.For example 8-(1-naphthyl)-bicyclooct-2-en-7-ols give substituted chrysenes in methanesulphonic acid.In the case of the homologous 7-aryl or 7,7-diarylbicyclohept-2-en-6-ols a novel transformation of diarylmethanes is observed.A mechanism is proposed which accounts for the product distribution observed in these rearrangements.
