Silver-Catalyzed Direct C–H Arylation of N-Iminopyridinium Ylides with Arylboronic Acids

Abstract A novel direct C–H arylation of N-iminopyridinium ylides with arylboronic acids has been developed. This reaction is performed at ambient temperature using inexpensive reagents: catalytic silver nitrate in the presence of potassium persulfate co-oxidant and give pyridyl arylation derivatives in moderate to good yields.
