A new ruthenium chloride complex featuring chirality derived from the face-specific coordination of the 1-Me-3-PhCp ligand has been successfully synthesized and resolved. The resolution has been achieved via the diastereomers of the (5)-alpha-methylbenzenemethanethiolate complex (1-Me-3-PhCp)Ru(dppm)(S)-C(S)(H)(Ph)(Me)}. The X-ray structures of (S-Cp,S)-(1-Me-3-PhCp)Ru(dppm)C(S)(H)(Ph)(Me)} and (R-Cp,S)-(1-Me-3-PhCp)Ru(dppm)C(S)(H)(Ph)(Me)} have been determined. Racemization has been observed at elevated temperatures, but a room-temperature conversion pathway provides access to the corresponding enantiopure acetonitrile, chloride, and hydride complexes.
