摘要
O-aryldithiophosphato and O-alkyldithiophosphato nickel complexes with diphosphine ligands have been synthesized by treatment of (diphosphine)NiCl2 {diphosphine = dppe (Ph2PCH2CH2PPh2), dppv (Ph2PCH = CHPPh2). dppb (1,2-(Ph2P)(2)C6H4)} with dithiophosphoric acid (RO)(2)P(S)SH (R = CH2CH3, CH2CH2Ph). The synthesis route is found to be an efficient pathway to prepare the O-alkyldithiophosphato and O-alkyldithiophosphato nickel complexes. All the complexes [Ni(S2P{O}OCH2CH2Ph)(dppe)] (1), [Ni(S2P{O}OCH2CH2Ph)(dppv)] (2), [Ni(S2P{O}OCH2CH2Ph)(dppb)] (3), [Ni(S2P{O}OCH2CH3)(dppe)] (4), [Ni(S2P{O}OCH2CH3)(dppv)] (5) have been fully characterized by elemental analysis and IR, H-1, C-13, P-31 NMR spectroscopies. In addition the molecular structures of 1-4 were established by X-ray crystallography. Crown Copyright (C) 2013 Published by Elsevier Ltd. All rights reserved.
