Abstract: Production of organic sulphoxides by the action of sulphoxides of lower molecular weight on organic sulphides in which the reaction is catalysed by one or more substances capable of supplying hydrogen ions to the reaction medium. The process permits yields to be obtained which exceed 90 percent, and the sulphoxide which is obtained is practically free from sulphone.

Abstract: Novel benzimidazole derivatives of the formula ##SPC1##Wherein R is alkyl of 1 to 2 carbon atoms and R.sub.1 is selected from the group consisting of tetrahydrofurfuryl, a saturated or unsaturated oxygen heterocycle of 4 to 5 carbon atoms and ##EQU1## wherein Z is unsaturated hydrocarbon radical of 2 to 4 carbon atoms having at least 2 halogen atoms which possess fungicidal activity.

Abstract: Novel bis-basic esters and amides of carbazole of the formula ##SPC1##Wherein:A. each of R.sup.1 and R.sup.2 is hydrogen, (lower)alkyl, cycloalkyl of 3 to 6 ring carbon atoms, alkenyl of 3 to 6 carbon atoms having the vinyl unsaturation in other than the 1-position of the alkenyl group, or R.sup.1 and R.sup.2 taken together with the nitrogen atom to which they are attached is pyrrolidino, piperidino, N-(lower) alkylpiperazino, or morpholino;B. each A is alkylene of 2 to about 8 carbon atoms and separates its adjacent Y and amino nitrogen by an alkylene chain of at least 2 carbon atoms;C. each Y is oxygen, or N--R wherein R is hydrogen, methyl or ethyl; andD. r.sup.3 is hydrogen or (lower) primary or secondary alkyl; or a pharmaceutically acceptable acid addition salt thereof. These compounds can be used as pharmaceuticals for preventing or inhibiting a viral infection.
