Chiral 1,3-diarylimidazolium salt carbene precursor, synthesis method therefor, metal salt compound and application thereof
Chiral 1, 3-diarylimidazole salt carbene precursors, their methods of preparation, particularly transition metal complexes and their use in chemical synthesis are provided. In particular, an air and moisture stable chiral 1, 3-diarylimidazole carbene precursor Cu (I) complex has been prepared and applied to highly regio- and enantioselective Markovnikov hydroboration of unactivated terminal alkenes to form chiral boronic esters. Moreover, these new chiral NHCs can be potentially applied in various metal-catalyzed asymmetric transformations. ##STR00001##
Azoline ring-containing compound, electron transport/injection layer material containing the same, and organic electroluminescent element using the same
An object is to provide an azoline ring-containing compound which achieves characteristics required for an organic EL element, such as a driving voltage, a quantum efficiency, and element lifetime in a well-balanced manner, and particularly can obtain a high quantum efficiency, for example, in a case where the azoline ring-containing compound is used for the organic EL element. The above object is achieved by an azoline ring-containing compound represented by the following general formula (1). ##STR00001## In formula (1), φ represents an m-valent group derived from an aromatic hydrocarbon having 6 to 40 carbon atoms or the like, Y represents —O—, —S—, or >N—Ar, R.sup.1 to R.sup.5 each represent a hydrogen atom or an alkyl having 1 to 4 carbon atoms, and L represents a phenylene group or the like.
