    Abstract: Biscarbamates, including novel one, of the general formula I where R is alkyl of 1 to 8 carbon atoms and X is a hydrocarbon radical of 2 to 60 carbon atoms in which one or more carbon atoms may be replaced by hetero atoms and which may contain halogen atoms or ester, carbonyl or nitrile groups are prepared by electrochemically oxidizing formamides of the general formula II in the presence of an alkanol of the formula ROH and of an ionic halide.

    Abstract: 1507920 Esters BASF AG 18 July 1975 [19 July 1974] 30186/75 Heading C2C [Also in Division C7] In electrochemical manufacture of an aromatic or heterocyclic ester by anodic acyloxylation of an aromatic or heterocyclic compound with an alkanoic acid, electrolysis is carried out in the presence of a conducting salt where R 1 , R 2 , and R 3 are the same or different and are H or alkyl, at least one being alkyl, and R 4 is H or C 1 -C 6 alkyl. The aromatic compound may be a benzene derivative, a naphthalene, anthracene, phenanthrene, acenaphthene, acenaphthylene, tetracene, perylene or chrysene; the heterocyclic compound may be quinoline or benzofuran; substituent groups on the aromatics may be alkyl, aryl, alkoxy, aryloxy, halogen, acyloxy, acylamino, cyano, nitro, or sulphonate; examples are given. Alkanoic acids mentioned are formic, acetic, propionic, butyric, valeric, isovaleric, and caproic; said salt may be made by reacting a suitable amine with such acid and may be trimethylammonium formate, acetate or propionate; triethyl ammonium formate, acetate or propionate, tri-n-butylammonium acetate, dimethylammonium formate, acetate or propionate, or diethylammonium acetate. The anode may be graphite, PbO 2 , Pt or Au, and the cathode graphite, Fe, steel or Pb; the electrode spacing may be 0À25-2 mm. and the C.D. 0À1- 30 A/dm. 2 ; a charge of 0À4-1À5 F/mole causes monoacyloxylation, and >2F/mole a higher degree. The electrolyte may comprise 5-60 wt. per cent aromatic or heterocyclic compound, 5-70% alkanoic acid, 1-20% of the salt and 0-50% of an inert co-solvent; everything apart from the product may be removed afterwards by distillation.

    Abstract: New bis-carbamates of the formula (I) R=1-8C alkyl gp., X= 2-60C atom-contg. hydrocarbon gp. in which 1 or more C atoms can be replaced by heteroatoms and which can contain halogen atoms, ester, carbonyl or nitro gps. are prepd. by electrochemical oxidn. of a formamide of formula (II) in the presence of an alcohol of formula ROH and an inorganic halide. - Pref. a salt of hydrobromic acid is used as the ionogenic halide, the anode is of graphite and methanol, is used as the alkanol. An electrolyte contg. 1-50 wt.% formamide of formula (II), 40-90 wt.% of the alkanol and 0.1-10 wt.% of the ionogenic halide is used for the electrochemical oxidn.
