Abstract: A process for the production of a chloride of thiophosphinic acids which comprises reacting an anhydride of a phosphinic acid with thiophosphoryl chloride.

Abstract: The invention relates to certain substituted phenoxypropionaldehyde derivatives, formulations of said derivatives and the use thereof for preemergence or postemergence control of noxious plants, i.e., weeds.

Abstract: New 3-(1-aminoalkylphosphinyl)-(2-substituted)propionic acids are described which display antibacterial activity and potentiate carbapenem antibiotics.

Abstract: A process for the preparation of phosphorus-containing .alpha.-amino nitriles of the general formula I ##STR1## in which R.sub.1 and R.sub.2 denote (substituted) alkyl, aryl, aralkyl or cycloalkyl, R.sub.3 denotes H, alkyl, phenalkyl, acyl, alkoxycarbonyl or aryloxycarbonyl, and n denotes zero or one, by reaction of corresponding acylals with alkali metal cyanides under the conditions of the Strecker synthesis.

Abstract: Compounds having the formula ##STR1## in which R is hydrogen, cyano or --COOR.sub.2 ; R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl; R.sub.2 is hydrogen or C.sub.1 -C.sub.4 alkyl; and Z is ##STR2## in which A is halogen, B is halogen or hydrogen and Y is nitrogen or --CH--, are herbicides.
