Clarifying carcinogenicity of ethylbenzene [PDF]
Regulatory Toxicology and Pharmacology, 2010 Ethylbenzene has been evaluated for carcinogenic activity in Fischer rats and B6C3F1 mice exposed by inhalation (Chan et al., 1998; Chan, 1999) and in Sprague-Dawley rats after oral exposure (Maltoni et al., 1985,1997). Bioassay findings are summarized below to expand on those not stated clearly or completely in Saghir et al. (2010).

C1-C8 volatile organic compounds in the atmosphere of Hong Kong: Overview of atmospheric processing and source apportionment [PDF]
, 2007 We present measurements of C1-C8 volatile organic compounds (VOCs) at four sites ranging from urban to rural areas in Hong Kong from September 2002 to August 2003. A total of 248 ambient VOC samples were collected.

Selective Hydrodemethylation of Methylalkylbenzenes on Potassium Hydride
Angewandte Chemie, EarlyView.Selective catalytic hydrodealkylation of methylalkylbenzenes on carbon‐supported potassium hydride is reported. The reaction exhibits a reactivity trend of 1° ∼ 2° ∼ 3° < CH3, which is opposite to traditional dealkylation and hydrodealkylation. DFT calculations on the (001) facet of KH with ortho‐ethyltoluene suggest that selectivity is controlled by ...

Harnessing Photoenzymatic Systems for Intermolecular C–H Fluorination
Angewandte Chemie, EarlyView.Despite the remarkable versatility of enzymes for catalyzing complex organic transformations under mild aqueous conditions, no biocatalytic system has been reported for intermolecular C–H fluorination. A radical photoenzymatic approach is introduced that leverages a designed de novo protein scaffold with an unnatural amino acid to achieve precise ...
