N- and O-arylation reactions of pyridin-2-ones as ambidentnucleophiles have been achieved with diaryliodonium salts on the basis of base-dependent chemoselectivity. In the presence of N,N-diethylaniline in fluorobenzene, pyridin-2-ones were very selectively converted to N-arylated products in high yields. On the other hand, the O-arylation reactions smoothly proceeded with the use of quinoline in chlorobenzene
The invention relates to metal complexes and to electronic devices, in particular organic electroluminescence devices, containing said metal complexes.
