Novel reaction of tetranitromethane (TNM) with electrophilic alkenes in the presence of triethylamine yielding substituted 3-nitroisoxazoles was found and studied. Triethylamine increases the ...

Moreover, both halogens are corrosive, difficult to handle and strong oxidants. 4 In addition, traditional halogenations of alkenes are performed in polychlorinated solvents, such as CHCl 3 or CCl 4 ...

Dichloroiodoisocyanuric acid was prepared in 93% by heating trichloroisocyanuric acid with 1.05 mol equiv. of iodine. This new reagent is very efficient for regioselective electrophilic iodination of ...

The direct anti-Markovnikov addition of strong Brønsted acids to alkenes remains an unsolved problem in synthetic chemistry. Here, we report an efficient organic photoredox catalyst system for ...

Multistep synthesis is a key capstone experience in organic laboratory instruction. Here, a four-step synthesis of avobenzone, an active component in sunscreens, has been developed that can be ...
