Title: ORGANOMETALLIC COMPLEX CATALYST
Abstract:
Provided is 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 π 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).
