An organic electroluminescence device including a cathode, an anode, and an emitting layer disposed between the cathode and the anode, wherein the emitting layer contains a compound represented by the following formula (1) and one or more compounds selected from the group consisting of compounds represented by formulas (11), (21), (31), (41), (51), (61), (71) and (81). In the formula (1), at least one of R
1
to R
8
is a deuterium atom.
The present invention provides a novel diazafluorene compound for manufacturing a 4,5-diazafluorene derivative. The diazafluorene compound is represented by the general formula (1):
wherein R
1
and R
2
each represent a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group, and may be the same or different from each other; and X
1
and X
2
each represent a halogen atom, and may be the same or different from each other.

Developing new strategies to enable chemo- and regioselectivereductions is an important topic in chemical research. Herein, an efficient and regioselective Pd/IPrBIDEA-catalyzed ring-opening hydrodefluorination of gem-difluorocyclopropanes to access terminal fluoroalkenes is developed. The success of this transformation was attributed to the use of 3,3-dimethylallyl Bpin as a novel hydride donor.

A process for preparing 2-fluoro-1-olefins or terminal bis-beta-fluoro-olefins which comprises reacting an appropriate allyl or alpha-olefinated starting material with phenylselenyl chloride and silver fluoride, and then reacting the intermediate phenylselenyl fluoride compound with ozone, and further reacting the resulting phenylselenoxide compound with an appropriate amine, to yield the desired fluorinated compounds.
