Feel the pinch! Planar–chiral, cationic, ruthenium–palladium complexes based on η6,η1‐coordinated ECE′ pincer ligands are synthesized as racemic mixtures by reacting ECE′–palladium complexes and [Ru(C5R5)(MeCN)3]+ arenophiles (R=H or Me). Chiral resolution of the cationic complexes was achieved by using the chiral counterion [Δ‐TRISPHAT]−, and solving the X‐ray crystal structure of one diastereoisomer
感到捏!平面手性,基于η阳离子,钌-钯配合物6,η 1配位的ECE'钳配体通过反应ECE' -钯复合物和合成的作为外消旋混合物的[Ru(C 5 - [R 5)(MeCN中)3 ] +亲爱的(R = H或Me)。通过使用手性抗衡离子[Δ-TRISPHAT] -并解决一种非对映异构体的X射线晶体结构,可以实现阳离子配合物的手性拆分。
