The Mechanism of Ruthenium‐Catalyzed Directed C─H Arylation of Arenes: The Key Role of Bis‐Cyclometalated Intermediates

Angewandte Chemie, EarlyView.
The mechanism of Ru‐catalyzed N‐directed C─H ortho‐arylation with haloarenes is addressed through experimental stoichiometric, catalytic kinetic, and DFT studies. These reveal a key role for bis‐cyclometallated ruthenium species and show bromoarene activation proceeds via a concerted oxidative addition.

Association of environmental exposure to perchlorate, nitrate, and thiocyanate with overweight/obesity and central obesity among children and adolescents in the United States of America using data from the National Health and Nutrition Examination Survey (NHANES) 2005–2016

New Directions for Child and Adolescent Development, Volume 2022, Issue 185-186, Page 107-122, November 2022., 2022
Abstract The association of overweight/obesity, and central obesity with thiocyanate (SCN), perchlorate (CIO), and nitrate (NO) in childhood and adolescence is unclear. Therefore, this study aimed to explore this association in 4447 participants comprising children and adolescents (aged 6–19 years) using data from the United States National Health and ...

Diamond Chemistry: Advances and Perspectives

Angewandte Chemie International Edition, Accepted Article.
Diamond as a material has many unique properties. More recently, diamond has emerged as a material with a wide range of applications in chemistry and biology. The high intrinsic stability of diamond, coupled with the ability to modify diamond surfaces with a wide range of species via highly stable covalent linkages, provides a wealth of opportunity to ...
