Scientists finally crack nature’s most common chemical bond
2020年5月26日 · The most common chemical bond in the living world — that between carbon and hydrogen — has long resisted attempts by chemists to crack it open, thwarting efforts to add new bells and whistles to old carbon-based molecules.

What happens when you explode a chemical bond?
2019年7月11日 · Since most chemical reactions occur rapidly, these fast-pulse lasers are key to “seeing” how the electrons that form the chemical bond behave when the bond breaks and/or reforms. Image: Yuki Kobayashi makes adjustments to an experiment in the basement of Hildebrand Hall.
Holy grails: seeking out selective C–H activation
2020年10月1日 · Source Royal Chemical Society. In a group of articles published in Chemistry World 25 years ago, the "holy grail" paper on the subject of C-H bond activation was penned by Bruce Arndtsen, Andrew Morley, Thomas Peterson …
Catalyst breaks only molecules’ toughest C–H bonds
2020年5月19日 · "There’s simply no other reaction in chemistry that will functionalise that carbon–hydrogen bond," says John Hartwig from the University of California, Berkeley, in the US about his team’s discovery: a catalyst that tackles the least reactive bond in a molecule. The reaction replaces the strongest primary C–H bond with a boron group.

2024年8月29日 · This chemical process employed three different bespoke heavy metal catalysts: one to add a carbon-carbon double bond to the polyethylene polymer and the other two to break the chain at this double bond and repeatedly snip off a carbon atom and, with ethylene, make propylene (C 3 H 6) molecules until the polymer disappeared. But the catalysts ...
