Rhodium-catalyzed transfer hydrogenation with functionalized bis(phosphino)amine ligands

A series of novel cationic mononuclear rhodium(I) complexes with the P-N-P ligands have been prepared starting from the complex [Rh(cod) 2]BF4. The structural elucidation of the complexes was carried out by elemental analyses, IR and multinuclear NMR spectroscopic data. Furthermore, the complexes were applied to the transfer hydrogenation of ketones in the presence of 2-propanol as the hydrogen source. Catalytic studies showed that all complexes are excellent catalytic precursors for the transfer hydrogenation of aryl alkyl ketones in 0.1 M iso-PrOH solution. Especially, [Rh((Ph2P)2N-C6H4-4-CH(CH 3)2)(cod)]BF4 acts as an excellent catalyst giving the corresponding alcohols in excellent conversion up to 99% (TOF ≤ 1980 h-1).

Trans- and cis-Ru(II) aminophosphine complexes: Syntheses, X-ray structures and catalytic activity in transfer hydrogenation of acetophenone derivatives

The ability of transition metal catalysts to add or remove hydrogen from organic substrates by transfer hydrogenation process is a valuable synthetic tool. For this aim, a novel Ru(II) complex with the P-N ligand [(Ph 2P)2NCH2/

Syntheses, structures, and catalytic ethylene oligomerization behaviors of Bis(phosphanyl)aminenickel(II) Complexes containing N-functionalized pendant groups

Several N-functionalized bis(phosphanyl)amine ligands respectively containing benzyl, furfuryl, thiophene-2-methyl, thiophene-2-ethyl, and 2-picolyl groups (la-e) were synthesized and characterized. The ligands reacted with (DME)NiBr2 in CH2Cl2 to give their corresponding nickel complexes [Ph2PN(R)PPh2NiBr 2] [R = CH2C6H5 (2a), CH 2C4H3O (2b), CH2C4H 3S (2c), CH2C5H4N (2d), and CH 2CH2C4H3S (2e)], The structures of these complexes were established by single-crystal X-ray crystallography, All these nickel complexes were highly active towards ethylene oligomerization in the presence of methylaluminoxane or Et2AlCl, producing a high content of butene (C4), Especially for 2e, which contains a thiophene-2-ethyl pendant group, the oligomerization products obtained at -40 °C contained 95.9 mol-% C4 fraction with 100 mol-% 1-butene. Over 50 °C, however, these nickel complexes underwent: Friedel-Crafts alkylation of toluene with ethylene and the olefin oligomers.
