Abstract:
The purpose of the present invention is to provide an N,N-bis(2-dialkylphosphinoethyl)amine-borane complex which is a ruthenium complex that exhibits excellent catalytic activity in a hydrogenation reaction, etc., and a production method therefor, and a method for efficiently producing a ruthenium complex containing N,N-bis(2-dialkylphosphinoethyl)amine as a ligand. The present invention is capable of efficiently producing an amine-borane complex (3) by reacting an oxazolidinone compound (1) with a dialkylphosphine-borane compound (2) in the presence of a base. The present invention is also capable of efficiently producing a ruthenium complex (5) by reacting the amine-borane complex (3) with a ruthenium compound (4) in the presence of an amine. (In the formula, a solid line, a dashed line, B, C, H, L 1 -L 3 , LG, n, N, O, P, Ru, X, and R 1 -R 10  are as defined in the description.)

Claim (Index 1):
A method for producing a compound having the following formula (3): wherein the solid line represents a single bond; B represents a boron atom, C represents a carbon atom, H represents a hydrogen atom, N represents a nitrogen atom, and P represents a phosphorus atom; R 1  and R 2  each independently represent an optionally substituted alkyl group or an optionally substituted cycloalkyl group; R 1  and R 2 , which are adjacent to each other, may bind together to form an optionally substituted ring; R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9  and R 10  each independently represent a hydrogen atom or a group selected from the group consisting of an optionally substituted alkyl group, an optionally substituted cycloalkyl group, an optionally substituted alkenyl group, an optionally substituted aryl group, and an optionally substituted aralkyl group; R 3  to R 10  may bind together to form an optionally substituted ring; n=2 to 3, and BH 3  is coordinated to a nitrogen atom or phosphorus atom, the method comprising: reacting a compound having the following formula (1): wherein the solid line represents a single bond, and the double line represents a double bond; C represents a carbon atom, N represents a nitrogen atom, and O represents an oxygen atom; LG represents a leaving group; R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9  and R 10  each independently represent a hydrogen atom or a group selected from the group consisting of an optionally substituted alkyl group, an optionally substituted cycloalkyl group, an optionally substituted alkenyl group, an optionally substituted aryl group, and an optionally substituted aralkyl group; and R 3  to R 10  may bind together to form an optionally substituted, with a phosphorus compound having the following formula (2): wherein the solid line represents a single bond, and the dashed line represents a coordination bond; B represents a boron atom, H represents a hydrogen atom, and P represents a phosphorus atom; R 1  and R 2  each independently represent an optionally substituted alkyl group or an optionally substituted cycloalkyl group; and R 1  and R 2  may bind together to form an optionally substituted ring, in the presence of bases.
