H_2O,MeOH,PhNH_2,Et_2NH)反应,通过切断邻苯二甲醛骨架上的磷桥,得到相应的[RP(H)A] M(CO)_6仲膦配合物(R= Ph,Me)。这些化合物的磷-氢键非常抗氧化。在一种情况下,它已成功地金属化t-BuOK在THE,然后,要么烷基化甲基碘或缩合与二苯甲酮。[PhP(H)-(NHPh)] W(CO)s的磷-氮键在室温下很容易被卤化氢裂解,得到第一个已知的稳定的仲卤代膦配合物[PhP(H)X] W(CO)6(X= Cl,Br,I)。氯代化合物与氨和NaSH在室温下反应,分别得到[PhP(H)NH 2] W(CO)5和S [PhPH-W-(CO)6] 2。在铝试剂存在下,氯代化合物歧化生成等量的[PhPH_2] W(CO)_6和[PhPCl_2] W(CO)_5。这些化合物均为稳定的化合物,其结构经~ 1H NMR、~(31)P NMR、IR、质谱和元素分析确证。
H20, MeOH, PhNH2, Et2NH) to give the corresponding [RP (H) A] M (CO) 6 secondary phosphine complexes (R= Ph, Me) through cleavage of thephosphorus bridge of the phos-phanorbornadiene skeleton. The phosphorus-hydrogen bond of these compounds is veryresistant toward oxidation. In one case, it has been successfully metalated by t-BuOK inTHE and, then, either alkylated by methyl iodide or condensed with benzophenone. The phosphorus-nitrogen bond of [PhP (H)-(NHPh)] W (CO) s is easily cleaved at room temperature by hydrogen halides to give the first known stable secondary halophosphine complexes [PhP (H) X] W (CO) 6 (X= Cl, Br, I). The chloro compound reacts with ammonia and NaSH at room temperature to give, respectively,[PhP (H) NH2] W (CO) 5 and S [PhPH—W-(CO) 6] 2. In the presence of aluminum trichloride, the dismutation of thechloro compound yields equal amounts of [PhPH2] W (CO) 6 and [PhPCl2] W (CO) 5. All these compounds are stable and have been completely characterized by 1H NMR, 31P NMR, IR, and mass spectrometry and elemental analyses.
