A novel binuclear metal complex containing a biimidazole as a bridging ligand. The binuclear metal complex can be used as a material for an organic electroluminescence element.

Binuclear metal complex, and organic electroluminescence element comprising same

The present invention relates to an (amide amino alkane) metal compound represented by the formula (1): wherein

(Amide amino alkane) metal compound, method of manufacturing metal-containing thin film using said metal compound

A substituted ethynyl gold-nitrogen containing heterocyclic carbene complex of formula (1): wherein L represents a nitrogen containing heterocyclic carbene ligand; X represents an alkyl, a cycloalkyl, an aryl, an aralkyl or a heterocyclic group; in which one or more hydrogen atoms on the carbon atom(s) of X may be replaced by a halogen atom, an alkyl, a cycloalkyl, an alkenyl, an aryl, an aralkyl, an alkoxy, an aryloxy, a dialkylamino, an acyl or an arylcarbonyl group; and, when more than one hydrogen atom on the carbon atom(s) of X is replaced by the alkyl, the alkenyl, the aryl, the aralkyl, the alkoxy, the aryloxy, the dialkylamino, the acyl or the arylcarbonyl group, the adjacent groups may be bonded together to form a ring, a method for preparing the same, and an organic electroluminescent device containing the same in at least one organic compound thin layer.

The present invention is directed to a substituted phenylethynylgold-nitrogen-containing heterocyclic carbene complex represented by the formula (1) or (2): wherein L represents a nitrogen-containing heterocyclic carbene ligand, and X represents an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group, a heterocyclic group, an alkoxy group, an aryloxy group, an alkylmercapto group, an arylmercapto group or a substituted amino group; and one or a plural number of hydrogen atoms on the carbon atom(s) of X are independently optionally replaced by a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, an alkylmercapto group, an arylmercapto group or a substituted amino group.

Substituted phenylethynylgold-nitrogen-containing heterocyclic carbene complex

In a process for preparing an optically active .beta.-hydroxyester derivative by enantioselective aldol addition reaction between an aldehyde and a ketene silylacetal, the enantioselective aldol addition reaction is performed in the presence of an organic base and a platinum-containing catalyst composed of an optically active bisphosphine-platinum complex having two P--Pt bondings which are equivalent to each other, showing in its .sup.31 P NMR spectrum a single peak assigned to P--Pt bonding.
