A nickel-catalyzed C–H cyanation reaction of arenes has been developed using 2-cyanoisothiazolidine 1,1-dioxide as an electrophilic cyanation reagent. Many different directing groups can be used in this cyanation to obtain a series of cyanation products with good yields. Adopting this strategy to introduce a cyano group, natural alkaloid menisporphine was successfully synthesized through cyano group
The present invention describes new types of metal complexes. Such compounds can be used as functional materials in a series of different types of applications which can be classified within the electronics industry in the widest sense.
The inventive compounds are described by the formulae (1) and (4).

To examine the effects of coordination sites and the nature of ligands reported for color-tuning of a few cyclometalated Ir(III) complexes, a series of 3'-substituted (F, CH3, OCH3, and CF3) phenylisoquinoline (piq) ligands were synthesized and successfully used to prepare iridium complexes, including bis[1-(5'-methyl) phenylisoquinolinato-N,C-2'] iridium(III) (acetylacetonate) (6a1), bis[1-(5'-trifluoromethyl) phenylisoquinolinato-N, C-2'] iridium(III) (acetylacetonate) (6a2), bis[1-(5'-methoxy) phenylisoquinolinato-N, C-2']iridium( III) (acetylacetonate) (6a3), and bis[1-(5'-fluoro) phenylisoquinolinato-N, C-2'] iridium(III) (acetylacetonate) (6a4). Density functional theory results indicate that two conflicting effects, electronic and steric, can be applied to account for the substitution-sensitive coordination sites of piq: the methoxyl- or fluoro-substituted ligand generates both 2'-coordinated and 6'-coordinated isomers. Coordination of methoxy substitution prefers 6'-coordination of piq dominated by steric effects, while coordination of fluoro substitution prefers 2'-coordination, arising from better back-donation of the iridium center. Correlations of HOMO-LUMO gaps with electroluminescence (EL) data are discussed. More importantly, the EL data are well predicted by time-dependent density functional theory calculations.
