Synthesis of New Chiral Heterobimetallic Chromium−Ruthenium Complexes by Regioselective Insertion of Ruthenium into the C−S Bond of Tricarbonyl-<i>η</i><sup>6</sup>-[(thiophenyl)arene]chromium Complexes
We report the synthesis of a series of chiral heterobimetallic complexes of the type [R = (η6-arene)Cr(CO)3, R‘ = H or R = H, R‘ = (η6-arene)Cr(CO)3] and one X-ray structure. All new complexes react with MeI, affording the analogous cationic complexes and the diamagnetic NMR chiral shift reagent TRISPHAT anion has been used to differentiate the enantiomers of a selected complex in solution.

A dearomative trifluoromethylative aminocarbonylation of arenesviabifunctionalcoordination to chromium has been firstly developed for amide construction, which expands the boundary of aminocarbonylations from conventional C=C bond substrates to arenes. Furthermore, a switchable 1,2-difunctionalization of arene C−H bonds and concise synthesis of amide-type drug analogs were successfully achieved
