• Synthesis of Transient and Stable <i>C</i>-Amino Phosphorus Ylides and Their Fragmentation into Transient and Stable Carbenes

  Deprotonation of 5b affords enamine 8, probably via fragmentation of ylide 6b into transient carbene 7b and a subsequent 1,2-hydrogen shift. Transient cyclic C-amino phosphorus ylides 6c and 6d have been prepared by intramolecular addition of a carbanion generated by deprotonation of a phosphorus substituent. Three-membered heterocycle 6c rearranges into alkene 9, whereas the four-membered ring system undergoes

  只有碱性膦，如三（二甲氨基）膦，才能合成稳定的无环 β-氨基鏻盐 1c，在与丁基锂去质子化后，得到相应的稳定 C-氨基磷叶立德 2c。相比之下，尽管存在弱碱性三芳基膦片段，但环状 β-氨基鏻盐 5a 和 5b 是稳定的。它们是通过将（氨基）（膦基）卡宾的卡宾中心插入到磷取代基的 CH 键中来制备的。5a 的去质子化导致相应的环状 C-氨基磷叶立德 6a，其已被充分表征，包括 X 射线衍射研究。5b 的去质子化得到烯胺 8，这可能是通过将叶立德 6b 裂解为瞬态卡宾 7b 和随后的 1,2-氢位移。瞬态环状 C-氨基磷叶立德 6c 和 6d 已通过分子内加成由磷取代基的去质子化产生的碳负离子来制备。三元杂环 6c 重排成烯烃 9，而四元环系统开环得到稳定的卡宾 7d。后者的结果为合成各种混合卡宾-膦双齿配体铺平了道路。

  Twenty-one adducts of the form AgNO3:ER3:L (1: 1: 1) (E = P, As, Sb; R = Ph, cy, o-tolyl, mes; L = 2,2'-bipyridyl ('bpy')-based ligand), together with AgNO3:Pcy(3):tPY (2:2:1) and AgNO3:PPh3:tPY (1:2:1) ('tpy' (2,2':6,2"-terpyridine)), have been synthesized and characterized by analytical, spectroscopic (IR, far-IR, H-1 and P-31 NMR) and single crystal X-ray diffraction studies. The resulting com plexes are predominantly of the form [(R3E)AgL]+NO3-, with trigonal EAgN2 coordination environments, the planarity of which is perturbed by the approach of the nitrate anion. The nitrate ion shows uni- or (semi-)bidentate coordination, excepting the complex AgNO3:P(o-tol)(3):doca (1: 1: 1) (dpca = bis(2-picolyl)amine) where the anion is uncoordinated, the donor dpca being a pincer-tridentate. The complex AgNO3:Pcy(3):tpy (2:2:1), also reported, is dinuclear with a bridging unidentate nitrate and a terpyridine, the latter bridging through its central ring, with the peripheral rings forming chelates to either side, whereas the complex AgNO3:PPh3:tpy (1:2:1) is ionic with a five-coordinate silver, bonded to tridentate tpy and two phosphines.
