  Design and synthesis of tris[bis(benzylammonium)aryl]phosphines with bulky meta-substituents

  摘要：

  A novel 3,5,3',5,3",5"-hexakis(dimethylamino)methyl substituted triphenylphosphine analogue has been prepared. The six amine functionalities of the corresponding phosphine oxide and sulfide were alkylated quantitatively with methyl iodide and benzyl bromide, as well as with G I and G2 Frechet dendrons to afford the respective hexa-ammonium triarylphosphine oxides and sulfides. The phosphine sulfide derivatives were deprotected with P(n-Bu)3 to afford a series of hexa-ammonium triarylphosphines that range from small molecules to first and second generation dendrimers (MW up to 5451.44). Upon formation of the hexa-ammonium salt a clear shift in P-31 NMR is observed, indicative for opening of the C-P-C angle of the triaryl phosphine. Calculations on the hexacationic phosphines show an increased barrier of rotation around the P-C(aryl) bond with increasing size of the N-substituents. The calculated structure of the G2-dendron alkylated hexa-ammonium triarylphosphine shows that this dendritic phosphine has a disc-like rather than a cone-like structure, with an estimated cone angle of approximately 180degrees (C) 2003 Elsevier Science Ltd.

  日期：2022.2.8

  A new system for the selective synthesis of bisdimethylamine derivatives using diols and aqueous dimethylamine as the starting materials was developed. An iridium complex bearing an N-heterocyclic carbene ligand was used as the catalyst, and the reaction proceeded based on the borrowing hydrogen strategy in an aqueous medium under mild conditions. Various bisdimethylamine derivatives were obtained

  Chromophores ranging from simple small molecule π-conjugated systems comprised of phenylene ethynylene or fluorenylethynyl units to cross-conjugated Bunz-type cruciforms have been derivatized to include 1,3-bis(dimethylaminomethyl)phenyl moieties. The photophysical responsiveness of these diamino-substituted chromophores to metal ions has been examined. Both emission enhancement (turn-on) and ratiometric fluorescence detection of Cu2+ and Zn2+ ions have been achieved in THF.

• Coulombic effects on the traceless Staudinger ligation in water
  作者：Annie Tam、Ronald T. Raines

  The traceless Staudinger ligation can be mediated by phosphinothiols under physiological conditions. Proximal positive charges are necessary to achieve that transformation, presumably because those charges discourage protonation of the key iminophosphorane intermediate. Here, a series of cationic phosphinothiols is used to probe Coulombic effects on the traceless Staudinger ligation in aqueous buffers
