An organic cation as a silver(I) analogue for the arylation of sp2 and sp3 C-H bonds with iodoarenes

Reactions promoted by stoichiometric amounts of silver salts suffer from high cost, limited availability and raise environmental concerns. This manuscript describes studies leading to the discovery of a general replacement for silver with an inexpensive and convenient organic salt in palladium catalyzed direct C(sp(2))-H and C(sp(3))-H arylation reactions.
