Gas-phase synthesis of hydroxyacetophenones by acylation of phenol with acetic acid
(Elsevier Science, 2004-09)
The gas-phase synthesis of aromatic ketones via acylation of phenol with acetic acid was studied on SiO2–Al2O3, Al-MCM-41, zeolites HY and ZSM5, and tungstophosphoric acid (HPA) supported on MCM-41 and carbon. At contact ...
Acylation of phenol on solid acids: Study of the deactivation mechanism
(Elsevier Science, 2005-10)
The deactivation mechanism of the gas-phase synthesis of o-hydroxyacetophenone (o-HAP) via acylation of phenol with acetic acid was studied on Al-MCM-41 and zeolites HY, HBeta and HZSM-5. The o-HAP yield remained constant ...
Synthesis and Crystal Structures of Octahedral Sn(IV) Complexes Prepared from SnCl(2)center dot 2H(2)O and 2-Hydroxyacetophenone (S-benzydithiocarbazate) Ligand (H(2)L)
(SPRINGER/PLENUM PUBLISHERS, 2011)
Two coordination octahedral Sn(IV) complexes [Sn(L)(2)] and cis-[SnCl(2)(L)(dmso)], where H(2)L is 2-hydroxyacetophenone (S-benzydithiocarbazate), were prepared and characterized by elemental analysis, IR, NMR ((1)H, (13)C), ...
Dithiocarbazate complexes with the [M(PPh(3))](2+) (M=Pd or Pt) moiety Synthesis, characterization and anti-Tripanosoma cruzi activity
(ELSEVIER SCIENCE INC, 2010)
New neutral Pd(II) and Pt(II) complexes of the type [M(L)(PPh(3))] (M Pd or Pt) were prepared in crystalline form in high-yield synthesis with the S-benzyldithiocarbazates and S-4-nitrobenzyldithiocarbazates derivatives ...
