It is an object of the present invention to provide a catalyst for a cross-coupling reaction in which an organometallic complex is sufficiently immobilized on a carrier and an object product can be easily obtained in a high yield and in a relatively short reaction time with a relatively small amount of use. The catalyst for a cross-coupling reaction of the present invention has a carrier part composed of a synthetic resin and an organometallic complex part immobilized on the carrier part by chemical bonding, and has a structure represented by formula (P1), wherein in (P1) R, Rmay be the same or different, and is a substituent such as a hydrogen atom. R, R, R, R, R, Rmay be the same or different and are substituents, such as a hydrogen. X represents a halogen atom, and Rrepresents a substituent having 3 to 20 carbon atoms with a π bond. RS1 represents the main chain of the synthetic resin precursors having —CHOH group at their end.

Cross-coupling reaction catalyst

An organometallic complex catalyst that makes it possible to obtain a higher yield of a desired product than conventional catalysts in a cross-coupling reaction. The organometallic complex catalyst has a structure represented by formula (1) and is for use in a cross-coupling reaction. In formula (1), M is the coordination center and represents a metal atom such as Pd or an ion thereof. R1, R2, and R3 may be the same or different and are a substituent such as a hydrogen atom. R4, R5, R6, and R7 may be the same or different and are a substituent such as a hydrogen atom. X represents a halogen atom. R8 represents a substituent that has a &#x3c0; bond and 3-20 carbon atoms. With regard to the electron-donating properties of R1-R7 with respect to the coordination center M of the ligand containing R1-R7 that is indicated in formula (2), R1-R7 are arranged in combination such that the TEP value obtained from infrared spectroscopy shifts toward the low frequency side compared to the TEP value of the ligand of formula (2-1).
