The reactivity of Ph3PNNC with a series of group 13 Lewis acids have been studied, and the corresponding Lewis acid–base adduct, zwitterionic product, and dimerized products have been isolated.
Group 13 aminoxy complexes, (L)E(TEMPO)3 (TEMPO = 2,2,6,6-tetramethylpiperidine 1-oxyl; L = THF (tetrahydrofuran) or Py (pyridine); E = Al, Ga, In), display ambiphilic reactivity with H2 and function as synthons for the preparation of materials.
Photosensitizer-free visible light-mediated cross-coupling of aryldiazonium tetrafluoroborates and alkynyltrimethylsilanes has been achieved using a recyclable SBA-15-anchored triphenylphosphine–gold(I) complex as a catalyst.
A new polymorphic modification of the well-known manganese(II) compound [(Ph3PO)2MnCl2] (where Ph3PO is triphenylphosphine oxide) was designed and investigated in terms of photophysics, electron paramagnetic resonance, and density functional theory.
Both metal-involved halogen bond activation and classical halogen bond activation are investigated in gold(I) catalysis of the propargylic amide cyclization reaction.
