Sodium dispersion promotes the reductive borylation of polycyclic aromatic hydrocarbons (PAHs) with MeOBpin. Anthracenes and phenanthrenes are converted to corresponding dearomatized diborylated products. The diborylation naphthalene-based small π-systems yields similar yet unstable products that oxidized into formal C–H unique regioselectivity. Pyrene is 1-borylpyrene without addition an oxida...
IMPORTANCE Polycyclic aromatic hydrocarbons are widespread urban air pollutants from combustion of fossil fuel and other organic material shown previously to be neurotoxic. OBJECTIVE In a prospective cohort study, we evaluated the relationship between Attention Deficit Hyperactivity Disorder behavior problems and prenatal polycyclic aromatic hydrocarbon exposure, adjusting for postnatal expos...
biodegradation of polycyclic aromatic hydrocarbons, toxic compounds widely distributed in the environment by bacteria, is a cheap and safe cleaning up method. the present study attempts to isolate and characterize dioxygenase-producing bacteria which are able to degrade phenanthrene and pyrene from refinery soils. it also aims to assess in vitro biodegradation. to do so, two contaminated soil s...
