为了深入研究整合型双膦配体对钼的双氮分子络合物中配位氮分子反应性的影响,本文详细地描述了配位双膦Ph(Et)CH_2CH_2P(Et)Ph的制备和一步法合成MO(N_2)_2[Ph(Et)PCH_2CH_2P(Et)Ph]_2[Ⅰ]j的试验。并报导了[Ⅰ]与 PhCN的置换反应。红外分析测得在化合物[Ⅰ]中V_(N≡N)=1950厘米~(-1)。化合物[Ⅰ]中的一个N_2被PhCN置换后,剩余之配位N_2的V_(N≡)=1928厘米~(-1);与此同时共配位PhCN之v_(C≡N)=2120厘米~(-1)均向低波数移动,文中还就双膦配体的合成路线及红外、质谱分析结果作了初步的讨论。在此之前,Mo(N_2)_2[Ph(Et)PCH_2CH_2P(Et)Ph]_2未见诸文献报导。
In order to further study the effect of the integrated bisphosphine ligand on the coordination nitrogen molecule reactivity in the dibasic molecular complexes of molybdenum, the preparation and the one-step synthesis of the coordination bisphosphine Ph (Et) CH 2 CH 2 P (Et) Ph are described in detail Syntheses of MO (N_2) _2 [Ph (Et) PCH_2CH_2P (Et) Ph] _2 [Ⅰ] j. And reported the displacement reaction of [I] with PhCN. Infrared analysis showed that V_ (N≡N) = 1950 cm -1 in the compound [I]. When a N_2 in compound [Ⅰ] is replaced by PhCN, V_ (N≡) = 1928 cm -1 of the remaining coordination N_2; meanwhile v_ (C≡N) = 2120 cm ~ (-1) all shift to low wavenumbers. The synthesis routes of bisphosphine ligands and the results of IR and mass spectrometry are also discussed. Previously, Mo (N_2) _2 [Ph (Et) PCH_2CH_2P (Et) Ph] _2 was not reported in the literature.
