Enantiomerically pure cyclic (R,R)-sulfates have been transformed into novel enantiopure ligands of the general type (S,S)-2,4-R2-1-(3-phenylpropyl)phosphetane (7a−c; R = Cy, i-Pr, t-Bu). 7a−c split the arene ruthenium complex dimer [RuCl2(η6-C6H5COOMe)}2] (8) by forming the mononuclear σ complexes (SC,SC)-[RuCl2(η6-C6H5COOMe)2,4-R2-1-(3-phenylpropyl)-η1-phosphetane}] (9a−c).
