Patent ID: 7985872

Claim:
A method for producing an olefin compound represented by the formula (2): wherein R 1 and R 2 are the same or different, and independently represent a hydrogen atom; an alkyl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; an alkenyl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; an aryl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C1-C3 alkylenedioxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; a heteroaryl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; an aralkyl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C1-C3 alkylenedioxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; or a heteroaralkyl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group, with the proviso that R 1 and R 2 are not hydrogen atoms at the same time, R 3 represents an alkyl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; an alkenyl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C6-C12 aryl group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; an aryl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C1-C3 alkylenedioxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; a heteroaryl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; an aralkyl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C1-C3 alkylenedioxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group; or a heteroaralkyl group which may be substituted with at least one selected from a group consisting of a halogen atom, a C1-C3 alkoxy group, a C6-C12 aryloxy group and a C2-C4 alkoxycarbonyl group, or R 1 and R 2 , or R 2 and R 3 may be bonded to form a ring together with carbon atoms to which they are bonded, which comprises contacting a palladium catalyst with an α,β-unsaturated aldehyde compound represented by the formula (1): wherein R 1 , R 2 and R 3 are the same as defined above, in the presence of an inorganic base.
