Direct functionalization of C−H bonds by electrophilic anions [PDF]
Significance Functionalization of unreactive molecules is a significant chemical challenge relevant to the conversion of abundant feedstocks such as alkanes into high-value chemicals. Herein, we demonstrate a new mechanism of alkane functionalization by the substitution of a proton by an anion in an alkyl chain.
