  摘要：

  The synthesis, oxidation and coordination chemistry of new bis(aminophosphines) based on diamines is demonstrated. Ph2PN(CH2Ph)CH2CH2(CH2Ph)NPPh2, (Pr2PN)-Pr-i(CH2Ph)CH2CH2(CH2Ph)(NPPr2)-Pr-i, Ph2PNH(C10H6)(2)NHPPh2, Ph2PNH(C10H6) (C6H4)NHPPh2 were prepared and tested in the hydroformylation of hex-1-to give aldehydes with poor selectivity (up to 1:b=2.5:1) to the desired linear products. Modelling calculations were performed for all ligands. R-2 groups enlarge the natural bite angle when going from R-2 = Ph-2 to R-2 = Pr-i(2) which are more bulky. Most of the ligands seem to be rigid (with flexibility ranges of 25degrees-46degrees). Four demonstrative X-ray structures are reported. (C) 2003 Elsevier Ltd. All rights reserved.
