General Description

1,1-Bipyrene, also known as 1,1'-biphenyl-4,4'-diyl, is a polycyclic aromatic hydrocarbon (PAH) consisting of two benzene rings connected by a single carbon-carbon bond. It is a byproduct of incomplete combustion of organic materials and is considered a potent carcinogen and mutagen. 1,1-Bipyrene is a highly persistent and bioaccumulative compound that is often found as a contaminant in air, water, and soil. It poses a threat to human health and the environment due to its toxicity and potential for long-term accumulation in the food chain. Stringent regulations and monitoring are necessary to control the release and exposure of 1,1-Bipyrene to protect human and environmental health.

Studies on pyrene and perylene derivatives upon oxidation and application to a higher analogue

The structure and electronic features of neutral and positively charged pyrene and perylene derivatives were explored. The radical cation of 1,3,6,8-tetraarylpyrene 1 was examined by ESR, UVvisNIR spectroscopy and theoretical calculations. The addition of

Nickel-Catalyzed Formal Homocoupling of Methoxyarenes for the Synthesis of Symmetrical Biaryls via C-O Bond Cleavage

A new method has been developed for the nickel-catalyzed homocoupling of methoxyarenes via C-O bond cleavage using a diboron reagent. The use of 1,3-dicyclohexylimidazol-2-ylidene as a ligand was found to be critical to the success of the reaction. This new method allows the synthesis of a wide range of biaryl compounds.

Pyrene dimerization into 1,1′-dipyrenyl

Treatment of pyrene and some its derivatives with Cu(II) tetrafluoroborate or perchlorate in CH3CN cleanly led to the formation of 1,1′-dipyrenyls. The other polycyclic hydrocarbons (anthracene, perylene) under the same conditions provide catio
