Transition-metal-free dehydrogenation coupling of pyridinium through a self-promoted hydride transfer process
A transition-metal-free intramolecular cross dehydrogenation coupling reaction of pyridinium was developed. The C(sp2)–H/C(sp2)–H coupling reaction involved an unprecedented intermolecular hydrideExpand
