Abstract
To improve a catalytic activity of a composite oxide, to carry out a reaction in a high yield, and to provide a synthesis reaction catalyst having excellent handling properties and a method of a synthesizing a compound using the same, a synthesis reaction catalyst containing a palladium-containing perovskite-type composite oxide having a specific surface area of 0.5 to 9.5 m2/g is used in Suzuki Cross-Couplings given by the following general scheme (14).
Claims2
A method for synthesizing a compound, which comprises reacting a compound represented by the general formula (2) with a compound represented by the general formula (3) or a compound represented by the general formula (4) in the presence of a synthesis reaction catalyst which contains a palladium-containing perovskite-type composite oxide represented by the general formula (1) having a specific surface area of 0.5 to 5.0 m2/g:
- AxB(l-y)PdyO3+σ (1)
- wherein A represents La;
- B represents Fe or FeCo;
- x represents an atomic ratio satisfying the following relation:
- 1.0≦x≦1.3;
- y represents an atomic ratio satisfying the following relation:
- 0<y≦0.5;
- and
- σrepresents an oxygen excess amount,
- R1—X (2)
- wherein R1 represents an aryl group which may have a substituent, a heterocyclic group which may have a substituent, or an alkenyl group which may have a substituent;
- and X represents a halogen atom, a trifluoromethanesulfonyloxy group, a p-toluenesulfonyloxy group or a methanesulfonyloxy group,
- R2-M (3)
- wherein R2 represents an aryl group which may have a substituent, a heterocyclic group which may have a substituent, or an alkenyl group which may have a substituent;
- M represents —B(ORa)2 group or —Sn(Rb)3 group;
- Ra represents a hydrogen atom or an alkyl group which may have a substituent;
- and
- Rb represents an alkyl group, and in stead of Ra, a ring including —OBO— may be formed through an arylene group which may have a substituent or an alkylene group which may have a substituent, both of which serve as a bond of —OBO—, and
- R3HC═CR4R5 (4)
- wherein R3, R4 and R5 each independently represents a hydrogen atom, an alkyl group which may have a substituent, an aryl group which may have a substituent, a carboxylic acid derivative, an acid amide derivative or a cyano group.
