Necula, Atena,Racoveanu-Schiketanz, Ana,Gheorghiu, Mircea D.,Scott, Lawrence T.
, p. 3448 - 3451 (1995)
Biphenyl (1) has beeen synthesized in four steps from benzoic acid.Treatment of 1 with AlX3/H2O (X = Cl or Br) in benzene under a variety of conditions scrambles the isotopic label in the biphenyl.With 10:1 AlBr3/H2O as the catalyst, complet
Studies in Negative Ion Mass Spestrometry. XIV.- Electron Attachment Reactions of a Series of η6-Arenetricarbonylchromium(O) Complexes
Blake, M. R.,Garnett, J. L.,Gregor, I. K.,Wild, S. B.
, p. 369 - 375 (1980)
Electron attachement rections of a series of (η6-arene)tricarbonylchromium(O) complexes have been examined in the gas phase.The electron capture process has been shown to be influenced by the structure of the η6-arene ligand and its
Experimental and Theoretical Studies on Gas-Phase Fragmentation Reactions of Protonated Methyl Benzoate: Concomitant Neutral Eliminations of Benzene, Carbon Dioxide, and Methanol
Xia, Hanxue,Zhang, Yong,Attygalle, Athula B.
, p. 1601 - 1610 (2018/07/29)
Protonated methyl benzoate, upon activation, fragments by three distinct pathways. The m/z 137 ion for the protonated species generated by helium-plasma ionization (HePI) was mass-selected and subjected to collisional activation. In one fragmentation path

Degani, Iacopo,Dughera, Stefano,Fochi, Rita,Gazzetto, Sonia
, p. 7228 - 7233 (2007/10/03)
A study was made of the isomerization reaction of a great variety of trimethyl α-keto trithioorthocarboxylates to α,α-bis(methylthio) thiolcarboxylates, intermediates of high synthetic value for the synthesis of α-arylpropionic acids. The reaction was carried out in methylene chloride in the presence of catalytic amounts of trityl perchlorate or methanesulfonic acid and was complete in 2 h at rt. In most of the investigated cases the result was positive, the yields usually being greater than 90%. Also the reaction mechanism was subjected to an experimental study.
The Formation of Phenylthiirene
