Electrofluorination of organic compounds

Electrofluorination of organic compounds. Beck, Fritz (BASF A.-G., Ger.). Ger. Offen. DE 2516355 28 Oct 1976, 11 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C25B003-08. 95-52-3 and 121-44-8 are cas registry numbers. These chemicals are also mentioned in this article. APPLICATION: DE 75-2516355 15 Apr 1975. DOCUMENT TYPE: Patent CA Section: 72 (Electrochemistry) Section cross-reference(s): 25, 26, 27 A process is described for electrochem. fluorination of arom. or heterocyclic org. compds. (such as alkylbenzenes, naphthalene, alkylanilines, benzimidazole, or phenothiazine) in MeCN as solvent contg. 0.1-20 wt.% free HF. The HF may be neutralized up to 50% by using an aliph. amine. Electrolysis is carried out in a capillary split cell with bipolar graphite electodes. For example, in the electrochem. fluorination of naphthalene(I), a mixt. contg. anhyd. MeCN 425, pure I 50 and 99% HF 24.6 g was electrolyzed at 1 A/dm2, at 15-20.degree.. The cell voltage at 1st was 50 V, but after 1 h fell to 18 V and then remained practically const. After 4.3 h and a theor. 100% exchange of current, the electrolysis was terminated. After sepn., the current efficiency for 1-fluoronaphthalene (II) [321-38-0] was calcd. to be 4.8% and for 2-fluoronaphthalene (III) [323-09-1] it was > 0.2%. Better results were obtained (21% for I and .apprx.1% for II) when triethylamine was added to the mixt. to neutralize the HF. .

Kinetic aspects of the electrochemical oxidation of halonaphthalenes

Kinetic aspects of the electrochemical oxidation of halonaphthalenes. Ortega, I.Some chemicals with cas registry numbers like 90-13-1 and 323-09-1 are also used. M.; Perez de Marquez, O.; Marquez, J. (Fac. Cienc., Univ. Los Angeles, Merida 5101, Venez.). Libro Mem. - Encuentro Nac. Electroquim., 4th, 275-86. Edited by: Sharifker, Benjamin R.; Suarez, I. J.; Mostany, J. L. Soc. Venez. Electroquim.: Caracas, Venez. (Spanish) 1991. CODEN: 57QKAK. DOCUMENT TYPE: Conference CA Section: 72 (Electrochemistry) Section cross-reference(s): 22, 25 A voltammetric study was undertaken for the oxidn. of monohalonaphthalenes to det. kinetic parameters by the method of Gorvachev reported by L. Antropov (1977). One irreversible oxidn. wave was obsd. in all cases. The substitution of halogens in naphthalene (naph) favored the rate of electron transfer. The Ea* values demonstrate simple diffusion processes, except for fluorinated samples which were anomalous. The general variation in the diffusion with respect to substituents was 2F < 2Cl < naph < F < Cl. .
