Ruthenium carbonyl clusters of diphosphazanes bearing axially chiral moieties

摘要

Reactions of Ru-3(CO)(12) with diphosphazane ligands bearing axially chiral moieties, X2PN(R)PY2 [R = Me, X-2 = Y-2 = C20H12O2 or C12H8O2; R = CHMe2, X-2 = C20H12O2, Y = OC6H5, OC6H4Me-4, OC6H4(OMe-4), OC6H4But-4 or C6H5; R = CHMe2, X-2 = C12H8O2, Y = C6H5] in the presence of benzophenone ketyl radical give the ruthenium carbonyl clusters, Ru-3(CO)10{mu-X2PN(R)PY2}. IR and NMR data for the complexes are reported. The structures of three complexes have been confirmed by single crystal X-ray crystallographic studies.
