Provided is a mononuclear ruthenium complex that comprises a ruthenium-silicon bond that is represented by formula (1) and that exhibits excellent catalyst activity in each of a hydrosilylation reaction, a hydrogenation reaction, and reduction of a carbonyl compound.
In formula (1), R 1 -R 6 either independently represent an alkyl group, an aryl group, an aralkyl group or the like that may be substituted with a hydrogen atom or X, or represent a crosslinking substituent in which at least one pair comprising one of R 1 -R 3 and one of R 4 -R 6 is combined. X represents a halogen atom, an organoxy group, or the like. L represents a two-electron ligand other than CO and phosphine. When a plurality of L are present, the plurality of L may be the same as or different from each other. When two L are present, the two L may be bonded to each other. n and m independently represent an integer of 1 to 3 with the stipulation that n+m equals 3 or 4.
摘要:
To efficiently and selectively recover scandium from an acid solution containing calcium, magnesium and scandium. In the present invention, an acid solution containing calcium, magnesium and scandium is brought into contact with a scandium recovering resin impregnated with an amide derivative represented by the following general formula for an hour or more. In the formula, R 1 and R 2 each represent the same or different alkyl groups. The alkyl group can be a straight chain or a branched chain. R 3 represents a hydrogen atom or an alkyl group. R 4 represents a hydrogen atom or any group other than an amino group, which is bound to the α carbon as an amino acid. The amide derivative is preferably any one or more of glycinamide derivatives, histidinamide derivatives, lysinamide derivatives and aspartic acid amide derivatives.

Provided is a novel compound that can be applied to an organic electronics element. More specifically, provided is a novel heterocyclic compound applicable to organic electronics elements such as an organic EL element, an organic solar cell element, an organic transistorelement and an organic semiconductor laser element. The compound is a heterocyclic compound represented by the following general formula (1):
wherein R 1 and R 2 independently represent a hydrogen atom, an aryl group that may have a substituent or an alkyl group that may have a substituent; m and n independently represent an integer of 1 to 4; and when R 1 and R 2 are two or more, one of R 1 's and one of R 2 's may be each the same as or different from one another.
