To provide a catalyst for synthesis reaction which can achieve good yield in the Sonogashira reaction and also can be recovered after the reaction, and a method for synthesizing a compound in which the catalyst for synthesis reaction is used, a perovskite-type composite oxide containing palladium is used as the catalyst for synthesis reaction in the Sonogashira reaction represented by the following reaction scheme (1): R.sub.1--X+HC.ident.CR.sub.2.fwdarw.R.sub.1C.ident.CR.sub.2 (1)
A catalyst for synthesis reaction that can allow the cross coupling reaction at an improved yield, and yet can be collected after used for the reaction and recycled, and a synthesizing method for a compound using the same catalyst for synthesis reaction. In the Suzuki cross-couplings given by the following reaction formula (15), palladium containing perovskite-like composite oxide is used as a catalyst for synthesis reaction: ##STR00001##
