Description
Summary:Synthesis of structure-controlled organometallic complexes based on the chemistry of polyphosphorus ligands OP[O(CH2)3PPh2]3 (1), PhP[O(CH2)3PPh2]2 (2), P[O(CH2)3PPh2]3 (3), P[O(CH2)10PPh2]3 (12), and PhP[O(CH2)10PPh2]2 (13), with [(μ-Cl)(1,5-C8H12)Rh]2, in which 1, 12, and 13 carry out a typical bridge-splitting reaction of peripheral phosphines with the Rh-dimer, while 2 and 3 complex with rhodium through bridgehead phosphite and two terminal phosphines leading to replacement of the 1,5-cyclooctadiene ligand also, is reported.
