The reaction between bis(M-chloro)bis[(i?)-l-[(dimethylamino)ethyl]naphthylenyl-C2,lV]dipalladium(II) and 2 mol of the bidentate Ph2PCH2CH2SMe gave a pair of internal diastereomeric complex cations arising from the coordinated sulfur stereocenter. The hexafluorophosphate salt of the diastereomeric mixture crystallizes as a compound with [a]D -35°( CH2C12) in the triclinic space group PI with a = 7.8690 (10) A, b = 17.837 (2) A, c = 21.830 (2) A, a = 82.86 (1)°, ß = 87.19 (1)°, y = 83.39 (1)°, and Z = 4 (R = 0.0412 and Rw = 0.0666). In solution, the complexes exhibit facile intramolecular asymmetric equilibration between diastereomers epimeric at sulfur at room temperature. A coalescence temperature of -90 °C was recorded for the interconversion by variable-temperature NMR spectroscopy. Similar behavior was observed for analogous complexes of Ph2AsCH2CH2SMe and

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
