Abstract: Aryl N-oxalyl-N-methyl-carbamates of the general formula ##STR1## in which X represents an alkoxy, alkenoxy, alkinoxy, aryloxy, alkylthio, alkenylthio, alkinylthio or arylthio radical, each of which may be optionally substituted or represents a radical of the general formula --N R.sup.3 R.sup.4, wherein R.sup.3 and R.sup.4 are identical or different and represent a hydrogen atom or an alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl or aryl radical, each of which may be optionally substituted, or the radicals R.sup.3 and R.sup.4, together with the N atom to which they are bonded, form an optionally substituted heterocyclic ring, andR.sup.1 represents an aryl radical which is optionally substituted,are novel and find use as pesticides, especially for combating insects, acarids and nematodes.

Abstract: The invention is insecticidal diaminoguanidine hydrazone compounds which are also effective antifeeding agents for insects and methods for their preparation.

Abstract: Unsymmetrical N-substituted bis-carbamoyl sulfide compounds exhibit exceptional broad spectrum pesticidal activity coupled with extremely low mammalian toxicity and phytotoxicity.

Abstract: Fumaric acid monoesters can be prepared by introducing a hydroxyl compound at a rate corresponding to the progress of the reaction into a solution or a melt of maleic anhydride, which may optionally be substituted, if appropriate in the presence of a cis-trans catalyst. New fumaric acid monoesters can be formed by the process.

Abstract: Aryl N-oxalyl-N-methyl-carbamates of the general formula ##STR1## in which X represents an alkoxy, alkenoxy, alkinoxy, aryloxy, alkylthio, alkenylthio, alkinylthio or arylthio radical, each of which may be optionally substituted, or represents a radical of the general formula --N R.sup.3 R.sup.4, wherein R.sup.3 and R.sup.4 are identical or different and represent a hydrogen atom or an alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl or aryl radical, each of which may be optionally substituted,or the radicals R.sup.3 and R.sup.4, together with the N atom to which they are bonded, form an optionally substituted heterocyclic ring, andR.sup.1 represents an aryl radical which is optionally substituted,are novel and find use as pesticides, especially for combating insects, acarids and nematodes.

Abstract: Symmetrical N-substituted bis-carbamoyl sulfide compounds exhibit exceptional broad spectrum pesticidal activity coupled with extremely low mammalian toxicity and phytotoxicity.

Abstract: New inter-m-phenylene-PGI.sub.2 derivatives are prepared of the general formula I ##STR1## wherein R.sup.1 stands for hydrogen, alkyl containing 1 to 4 carbon atoms or a pharmaceutically acceptable primary, secondary, tertiary or quaternary ammonium cation or a metal cation,R.sup.2 and R.sup.3 stand independently on each other for hydrogen, alkanoly, aroyl or an acetal type or alkyl silyl type protecting group,R.sup.4 represents hydrogen or an alkyl group containing 1 to 4 carbon atoms,X stands for oxygen, or a--CH.sub.2 --group,Y stands for--C.tbd.C-- or a trans--CH.dbd.CW group, wherein W stands for chlorine, bromine or fluorine,Z represents an alkyl group having 6 to 9 carbon atoms, optionally substituted by one or more alkyl groups containing 1 to 4 carbon atoms or fluorine or it stands for an optionally substituted arylmethyl or aryloxy methyl group.The new compounds are active ingredients of pharmaceutical compositions having antiaggregatory activity.

Abstract: N-[1-(2'-substituted-alkyl)-amidomethyl and carboalkoxymethyl]-substituted-N-acylanilines have fungicidal activity.

Abstract: 16-Fluoro-13,14-dehydro-PG.sub.2 series have been prepared, and their pharmaceutical use.

Abstract: A process for protecting cultivated plants against aggressive agricultural chemicals is described in which oxime derivatives of the formula ##STR1## are used as antidotes. Either the cultivated area for the cultivated plants or the cultivated plants themselves or parts of the plant (seeds, tubers, stem parts and the like), as desired, can be treated with these oxime derivatives, which are used as a dressing.

Abstract: Carbamate-sulfenyl-carba moyl fluoride compounds are valuable insecticidal compositions and are also useful intermediates in the production of bis-carbamate compounds.

Abstract: 16-Fluoro-prostaglandins and pharmaceutical compositions containing the same are prepared. They are useful, for example, as anti-ulcer agents.

Abstract: Novel carbamates derived from substituted cyclic .beta.-keto-alcohols, their preparation, and pharmaceutical formulations which contain these compounds and which may be used as hypnotics in the treatment of sleep disturbance and as sedatives.
