2-phenyl-6-azolylpyridine-based ligand and group VIII transition metal complex

摘要

A 2-phenyl-6-azolylpyridine-based ligand is represented by the following formula (I):; ;wherein, X represents nitrogen or C—R¹⁰; R¹, R², R³, R⁴, R⁵, R⁶, R⁷, R⁸ and R¹⁰ independently represent hydrogen, halogen, a cyano group, an amino group, an optionally substituted aryl group, an optionally substituted heteroaryl group, sulfate, —COOH, an alkoxy group, a carbonyl group, a C₁-C₁₀ haloalkyl group, a C₁-C₁₂ alkyl group, a C₂-C₁₀ alkenyl group, a C₂-C₁₀ alkynyl group, a C₃-C₂₀ cycloalkyl group, a C₃-C₂₀ cycloalkenyl group, a C₁-C₂₀ heterocycloalkyl group, or a C₁-C₂₀ heterocycloalkenyl group; and R⁹ represents hydrogen or alkali metal.
