Abstract

Feel the pinch! Planar–chiral, cationic, ruthenium–palladium complexes based on η^6^,η^1^‐coordinated ECE′ pincer ligands are synthesized as racemic mixtures by reacting ECE′–palladium complexes and [Ru(C~5~R~5~)(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 (shown here).magnified image

Base degradation of the prochiral 1-diphenylphosphanyl-2phenyl-1,2-dicarba-closo-dodecaborane (1) affords the planar-chiral 7-diphenylphosphanyl-8-phenyl-7,8-dicarbanido-undecaborate anion (2). Resolution of the racemic anion carried out using a well-established procedure, gave the internally diaste
