effective methodology for the cross-coupling of heteroaryl iodides with NN–AuPPh3 at room temperature is reported. The protocol is based on a novel catalytic system consisting of Pd2(dba)3·CHCl3 and the phosphine ligand MeCgPPh having an adamantane-like framework. The present protocol was found to be well compatible with various heteroaryl iodides, thus opening new horizons in directed synthesis of functionalized

A tetraradical with a triplet ground state and a nearby excited quintet state, high thermal stability, and reversible redox waves has been prepared by using the palladium-catalyzed cross-coupling reaction of a triiodo-derivative of benzotriazinyl radical with a gold(I) nitronyl nitroxide-2-ide complex in the presence of an efficient catalytic system: Pd2(dba)3/MeCgPPh.
