are independently selected from the group consisting of a hydrogen atom, a straight or branched alkyl group having 1 to 4 carbon atoms, and a substituted or unsubstituted aromatic hydrocarbon group having 6 to 22 carbon atoms.
The present invention relates to metal complexes and to electronic devices, in particular organic electroluminescent devices, containing these metal complexes.
powerful approach toward the functionalization of C–H bonds remote to a functional group. Whereas various Pd-catalyzed migratory cross-couplings have been developed in the past years, the design of an efficient migratory version of the popular Suzuki–Miyaura cross-coupling has remained elusive. The current article reports a one-pot procedure consisting of alkene hydroboration and migratory Suzuki–Miyaura
