SN1 and SN2 reactions are fundamental types of nucleophilic substitution in organic chemistry, each with distinct mechanisms and characteristics. An SN1 reaction (Substitution Nucleophilic ...

As global energy and environmental challenges intensify, solar-driven photocatalysis has emerged as a promising pathway for sustainable chemical conversion. Metal halide perovskites (MHPs), with their ...

Our theories would not have been possible to validate or investigate if we didn’t have leadership computing power. - Santanu Roy, R&D staff in the Chemical Sciences Division at ORNL Using the ...

The photodriven radical-mediated [3 + 2] cyclization reaction was found to yield polymers efficiently without being hindered by degradative chain transfer. The first reaction is a hydrogen abstraction ...

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 ...

Multisubstituted allylic boronates are attractive and valuable precursors for the rapid and stereoselective construction of densely substituted carbon skeletons. Herein, we report the first synthetic ...

Vicinal dihalides—molecules that feature halogen atoms on adjacent carbons—are useful as flame retardants, as pesticides, and as intermediates en route to polymers and pharmaceuticals. But making ...

ABSTRACT: Colloidal silver nanoparticles were prepared by reducing silver nitrate with oxalic acid in presence of cetyltrimethylammonium bromide (CTAB). The synthesized silver particles show an ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
