| abstract | 1,127,368. Making cyclic organic compounds electrolytically. MONSANTO CO. 3 Dec., 1965 [4 Dec., 1964], No. 51430/65. Heading C2C. [Also in Division C7] Cyclic organic compounds are made electrolytically using as starting material an organic compound containing two ethylenic groups each in α,# position relative to an electronwithdrawing group, which compound is dissolved in an aqueous salt electrolyte, e.g. a solution of an organic sulphonate, alkyl sulphate or amine or quaternary ammonium salt, the electrolysis effecting reductive hydrodimerization at the # carbon atoms forming a ring and saturating the ethylenic linkages. The electronwithdrawing groups are e.g. carboxylate, carbonamide, nitrile, phosphonium, 2-pyridine and 4-pyridine. The ethylenic groups are linked by a bivalent organic chain which is hydrocarbon except for one or more ether, thioether, imino or carboxyl groups and which may contain arylene groups as well as aliphatic hydrocarbon groups. This bivalent organic radical may consist of one or more groups of the formulµ -CR 2 -, -NR-, -O- -CO- or phenylene, there being at least one and at most 5 -CR 2 - groups, at most 2 -NR- groups, at most 2 -O- groups, at most 2 -CO- groups and at most one phenylene group, and the total number of such groups being from 1 to 8, R being hydrogen or lower alkyl and there being no -O- adjacent to an -NR-. Typical reactions are Z being the bivalent chain and Y the electronwithdrawing group. Z may also be a cyclic group yielding a double ring compound. Examples of products of the electrolysis include inter alia 2,3-dicarbethoxymethyl-1,4-dioxane and 3,4 - bis - (dicarbethoxymethyl) - 1,2,3,4 - tetrahydroquinoxaline. The electrolyte may contain at least 5%, and preferably at least 30% of ionizable salt and the anolyte and catholyte may be separated by a membrane, e.g. an ionexchange membrane or unglazed porcelain pot. To minimize polymerization of the organic compound and other undesired reactions, the pH should be maintained in the range 3-12, preferably 6-9À5. Inhibitors to prevent polymerization may be added. Cathode current densities may range from 10 to 100 or more amps per square decimeter. |
