Synthesizing method for compound, and catalyst for synthesis reaction

A synthesizing method for a compound, wherein a compound indicated in a formula (1) given below, and a compound indicated in a formula (2) given below or a compound indicated in a formula (3) given below are allowed to react with each other in the presence of a perovskite-like composite oxide comprising palladium:

• R1—X (1)
• wherein in formula (1), R1 represents an aryl group that may have a substituent, a heterocyclic group that may have a substituent, or an alkenyl group that may have a substituent, and X represents a halogen atom, a triflouromethanesulfonyloxy group, a p-toluenesulfonyloxy group, or a methanesulfonyloxy group;
• and
• R2-M (2)
• wherein in formula (2), R2 represents an aryl group that may have a substituent, a heterocyclic group that may have a substituent, or an alkenyl group that may have a substituent, M represents a —B(ORa)2 group or a —Sn(Rb)3 group, Ra represents a hydrogen atom or an alkyl group that may have a substituent, and Rb represents an alkyl group;
• wherein as a substitute for Ra, an arylene group that may have a substituent or an alkylene group that may have a substituent may be used as a bonding hand of —OBO—, to form a ring including the —OBO—;
• and
• R3HC ═CR4R5 (3)
• wherein in formula (3), R3, R4, and R5 each represent a hydrogen atom, an alkyl group that may have a substituent, an aryl group that may have a substituent, a carboxylic acid derivative, an acid amide derivative, or a cyano group.
