摘要： Provided is, for example, an exhaust gas-purifying three-way catalyst which is small in the amount of a platinum group element used, which can be early increased in temperature to a catalytically active temperature, which is suppressed in degradation in performance due to a catalyst poison included in an exhaust gas even if placed directly under an engine, and which is excellent in purification performance. An exhaust gas-purifying three-way catalyst including at least a catalyst carrier 11 and a catalyst layer 21, wherein the catalyst layer 21 has a layered structure having at least a first catalyst layer L1, a second catalyst layer L2 and a third catalyst layer L3 in the listed order, the first catalyst layer L1 contains a first composite catalyst particle including palladium supported on a first base material particle, the second catalyst layer L2 contains a second composite catalyst particle including rhodium supported on a second base material particle, the third catalyst layer L3 contains a third composite catalyst particle including palladium supported on a third base material particle, and the total coating weight Wt in the catalyst layers L1, L2, and L3 (provided that the platinum group element included in each of the catalyst layers is excluded) is 110 g/L or more and 225 g/L or less in total, per volume of the catalyst carrier 11.

摘要： 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).
