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 ...
De-Wei Gao's research group at ShanghaiTech University has developed a new method for efficient and highly selective ...
A research team has developed a reaction for creating functionalized ketones. Using an N-heterocyclic carbene (NHC) organocatalyst, with no need for metals or light irradiation, an acyl and an alkyl ...
Osaka — Free radicals don't get the best press. However, while they are known as harmful oxidants in the body, these ultra-reactive chemicals are indispensable in the lab. Radical reactions play a ...
ESR spectra of short-lived radicals made by photolysis at room temperature of acidic alcoholic solutions of imidazole, 1-methylimidazole, and 4(5)-methylimidazole containing acetone or hydrogen ...
Chemists have a few choices when they want to transform aromatic C–H bonds into something more complicated. Brominating and borylating these bonds are popular options, but those reactions usually ...
This is a preview. Log in through your library . Abstract Radical formation in the reactions of hydrogen atoms with some cystinefree proteins and polyalanine was investigated by both ESR and ...
Researchers have converted methane into valuable chemicals. The reaction occurs under ambient conditions in a novel two-phase system. Chlorine radicals are generated by light irradiation in water ...
