Title:
The partial hydrogenation reaction of an alkyne derivative
Document Type and Number:
Japanese Patent JP6005625
Kind Code:
B2
Abstract:
The invention relates to a method for producing an alkene derivative represented by general formula [4] (wherein R1 represents an aryl group having, as a substitute, an alkyl group, an alkoxy group, a halogen atom, an amino group, or a nitro group, an aryl group having no substituent, or an alkyl group; and R2 represents a hydrogen atom, an alkyl group, a hydroxyalkyl group or an alkoxycarbonyl group), characterized by comprising reducing an alkyne derivative represented by general formula [1] (wherein R1 and R2 are the same as above) by bringing the alkyne derivative into contact with a hydrogen source in the presence of (I) silica or titanium oxide, which supports palladium having a particle diameter of 0.3 to 10 nm, and a sulfur compound represented by general formula [2] (wherein R3 and R4 each independently represent an alkyl group or an aryl group) or/and general formula [3] (wherein R5 and R6 each independently represent an alkyl group or an aryl group) in an amount 1 to 1000 times the mole of palladium, or in the presence of (II) silica or titanium oxide, which supports palladium having a particle diameter of 0.3 to 10 nm and has a sulfoxide group.
