Making molecules with quaternary carbon bonds—four carbons attached to a central C—is tricky but necessary for medicinal chemists. Quaternary C bonds have a discrete shape, Princeton University ...

Organocatalysts consisting of organic compounds without metal elements are receiving much attention as next generation catalysts in the hope of reducing environmental burden and coping with exhaustion ...

Alcohol-based direct radical C-C bond formation reactions. Upper arrow: reactions without trapping agent. Lower arrow: reactions with radical-trapping agents (electron-deficient alkenes). Disclaimer: ...

A team of Boston College researchers has demonstrated an unprecedented catalytic approach that enables concurrent control of multiple convergences and selectivities in intermolecular amination of ...

A novel treatment for recurrent localized cervical cancer using point-of-care ethyl cellulose ethanol ablation with concurrent cytotoxic therapy. This is an ASCO Meeting Abstract from the 2021 ASCO ...

The latest short science news items from C&EN. The researchers trigger the reaction with violet light. First, there is an electron transfer from an oxidant, a N-alkoxyphthalimide ester, to the ...

Asthma may not be driven by the molecules scientists have blamed for decades. Researchers have identified “pseudo leukotrienes,” inflammation-triggering compounds formed by uncontrolled free-radical ...

To improve water treatment, researchers use modeling to understand how chemical byproducts form during the advanced oxidation process. Synthetical chemicals are ever-present in modern life—in our ...

Mitigation of the ozone-pollution problem is complicated by the fact that ozone (O 3) is a secondary pollutant; that is, it is not emitted directly into the atmosphere, but is produced by ...
