A nickel-catalyzed reductive coupling of aryl triflates with thiocarbonates is reported here. Both electron-rich and -deficient aryl C(sp2)-O electrophiles as well as a class of O-tBu S-alkyl thiocarbonates are compatible with the optimized reaction conditions, as evidenced by 49 examples. The reaction also proceeds with good chemoselective cleavage of the C-O bond with regard to thioesters. This work broadens the scope of nickel-catalyzed reductive cross-electrophile coupling reactions.

Paragraph 0119, (2018/03/09)
To provide a light-emitting material containing a compound having a high excitation triplet level, particularly a host material of a light emitting layer, as a material for an organic electroluminescent device with high efficiency, and also to provide an organic electroluminescent device with high efficiency and high luminance by using the material. A light-emitting material containing a compound having a carbazole ring structure represented by the following general formula (1), and an organic electroluminescent device containing a pair of electrodes and one layer or plural layers including at least a light emitting layer intervening between the electrodes, the light emitting layer containing as a constitutional material thereof the light-emitting material.
