A team of researchers from the University of Science and Technology of China and the University of California has found a way to use radicals to break C-F bonds one at a time when working with trifluoroacetamides and acetates. ...
The formation of double bonds between two carbon atoms (C=C) is of central significance in natural organisms. The vast majority of natural substances therefore contain one or more of these double bonds. Compounds with C=C ...
