Abstract

A method for producing ruthenium compound including the step of reacting a compound represented by General Formula (1): RuL 0 2 (wherein L 0 represents an unsaturated hydrocarbon compound having 4 to 10 carbon atoms and at least two double bonds) with trifluorophosphine or reacting the compound represented by General Formula (1) with trifluorophosphine, and hydrogen or a halogen to obtain a compound represented by General Formula (2): Ru(PF 3 ) l (L 1 ) m (L 2 ) n (wherein L 1 represents a hydrogen atom or halogen atom, L 2 represents an unsaturated hydrocarbon compound having 4 to 10 carbon atoms and at least two double bonds, l is an integer from 1 to 5, m is an integer from 0 to 4, and n is an integer from 0 to 2, provided that l+m+2n=5 or 6). With this method, a trifluorophosphine-ruthenium compound can be synthesized under low-temperature and low-pressure conditions.

Claims (8)

1. A method for producing ruthenium compound, comprising the step of reacting a compound represented by General Formula (1) described below with trifluorophosphine, or reacting the compound represented by General Formula (1) described below with trifluorophosphine and at least one selected from hydrogen and halogen to obtain a compound represented by General Formula (2) described below:

RuL 0 2   (1)

(in General Formula (1), L 0 represents an unsaturated hydrocarbon compound having 4 to 10 carbon atoms and at least two double bonds, and the two L 0 in General Formula (1) may be the same or different);

Ru(PF 3 ) l (L 1 ) m (L 2 ) n   (2)

(in General Formula (2), L 1 represents a hydrogen atom or a halogen atom, and when there are more than one L 1 , these L 1 may be the same or different, L 2 represents an unsaturated hydrocarbon compound having 4 to 10 carbon atoms and at least two double bonds, and when there are more than one L 2 , these L 2 may be the same or different, l is an integer from 1 to 5, m is an integer from 0 to 4, and n is an integer from 0 to 2, provided that l+m+2n=5 or 6).

2. The method for producing ruthenium compound according to claim 1 , further comprising the step of reacting a compound represented by General Formula (3) described below with an unsaturated hydrocarbon compound having 4 to 10 carbon atoms and at least two double bonds to obtain the compound represented by General Formula (1) described above:

RuX j   (3)

(in General Formula (3), X is a halogen atom, and j is an integer of 2 or 3).
