The tetrahedral geometry of four-coordinate carbon atoms is a steadfast property of organic compounds. Nevertheless, chemists are still attracted to the possibility of twisting or squashing a ...
To celebrate C&EN’s 90th anniversary, one Editor’s Page each month examines materials from C&EN Archives. Featured articles are freely downloadable for one month. The tetrahedral geometry of, and the ...
Planar tetracoordinate carbon species subvert the long‐standing paradigm of tetrahedral carbon geometry, demonstrating that a carbon atom can be stabilised in a planar configuration with four ...
Due to their well-defined three-dimensional geometry, spiro compounds are widely utilized in drug research. From the central tetrahedral carbon atom, besides the regular structure, an inverted spiro ...
Tetrahedral kites make for a great DIY project. Originally developed by Alexander Graham Bell, these simple kites can be built out of straws, fishing line and paper. The weight to sail area coupled ...
