Singewald, Elizabeth T. published the artcileNovel Hemilabile (Phosphinoalkyl)arene Ligands: Mechanistic Investigation of an Unusual Intramolecular, Arene-Arene Exchange Reaction, Computed Properties of 622-86-6, the main research area is crystal structure rhodium phosphinoethoxybenzene complex; mol structure rhodium phosphinoethoxybenzene complex; intramol exchange free coordinated arene rhodium; phosphinoalkylarene ligand preparation complexation rhodium; phosphinoalkoxyarene ligand preparation complexation rhodium; rhodium phosphinoalkoxyarene phosphinoalkylarene complex preparation; hemilabile phosphinoalkylarene ligand rhodium complex.
The novel, hemilabile (phosphinoalkyl)arene ligands ArX(CH2)2PPh2 (Ar = C6H5, X = O; Ar = C6H5, X = CH2; Ar = 4-FC6H4, X = CH2) were synthesized and complexed to Rh(I) to form the bis(phosphine), η6-arene piano stool complexes [(η6:η1-ArX(CH2)2PPh2)Rh(η1-ArX(CH2)2PPh2)]BF4 (2a-c; shown as I, Y = H, H, F, resp.). Complexes 2a-c were fully characterized in solution, and complex 2a was characterized by single-crystal x-ray diffraction methods. Two of these complexes, 2a and 2c, undergo an unusual, degenerate η6-arene, free arene exchange reaction which was studied by 2-dimensional NMR EXSY experiments A mechanism for the exchange reaction of 2a which involves the formation of a square planar, cis-phosphine, cis-ether Rh(I) complex, [Rh(η2-PhO(CH2)2PPh2)2]BF4, is proposed.
