Abstract: A compound of the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3, which may be same or different, are each hydrogen or C.sub.1 -C.sub.4 alkyl, X is chlorine or bromine, Y is hydrogen, chlorine, bromine, fluorine or iodine and Z is N,N-dimethylamino, N-methoxy-N-methylamino, C.sub.1 -C.sub.4 alkyl or C.sub.3 -C.sub.6 cycloalkyl, which is useful as a herbicide.

Abstract: The present invention relates to the use of telluroxides as mild and selective oxidizing agents serving to oxidize certain functions, notably >C.dbd.S groups, in the presence of other relatively easily oxidized functions which remain unaffected; telluroxides of interest as oxidizing agents include, for example, compounds of the formula: ##STR1## wherein R and R.sup.1, which may be the same or different, each represent an optionally substituted aryl or heterocyclic group; or R and R.sup.1 together with the tellurium atom therebetween represent a heterocyclic ring, which may contain one or more further heteroatoms, and which may carry substituents and/or fused aromatic rings.

Abstract: Ketoester of the formula ##STR1## .alpha.-carboxylate-.omega.-acyl fluoride of the formula ##STR2## vinyl ether of the formula ##STR3## divinyl ether of the formula ##STR4## allyl ether of the formula ##STR5## and film-forming copolymers, useful as molding resins, of the vinyl ether and/or the divinyl ether or the allyl ether and a fluorinated vinyl monomer, for example, tetrafluoroethylene, wherein, in the above formulas, n is 0 to 6, p is 0 to 7, X is CO.sub.2 M, CO.sub.2 R, CO.sub.2 H, CONH.sub.2, COF, COCl or CN, M is alkali metal, ammonium or quaternary ammonium and R is C.sub.1-8 alkyl, selected copolymers, after hydrolysis, being water-wettable and dyeable, exhibiting ion-exchange properties and being useful in curable fluoroelastomer compositions and, in film form, as the membrane in a chloroalkali electrolysis cell.

Abstract: N-.alpha.-Alkoxyalkyl-carboxamides are prepared by reacting primary or secondary amides of aliphatic, araliphatic or aromatic carboxylic acids, or cyclic carboxamides (lactams) which are not capable of forming an aromatic system, with open-chain .alpha.-halogenoalkyl ethers with at least 3 C atoms per molecule, in the presence of tertiary amines. N,N-Bis-.alpha.-alkoxyalkylcarboxamides can also be obtained from the primary carboxiamides. The reaction products, of which the compounds V and VI: ##STR1## wherein R.sup.4 =C.sub. -C.sub.4 -alkyl and R.sup.5 =CH.sub.3 or C.sub.2 H.sub.5, are new, are intermediates mainly for the preparation of N-alkenyl- or N-vinyl-carboxamides, of which, in turn, the compounds VII are new: ##STR2## The N-alkenyl- or N-vinyl-carboxamides can themselves be processed to give valuable homopolymers and copolymers.

Abstract: Process for the preparation of an alpha-hydroxycarboxylic acid amide compound of the formula ##STR1## wherein R.sup.1 is hydrogen or alkyl; andR.sup.2 and R.sup.3 are individually selected from hydrogen, alkyl, alkenyl, alkynyl, aralkyl, cycloalkyl or aryl, each of which may be optionally substituted, or a nitrogen-containing heterocyclic radical; orR.sup.2 and R.sup.3, together with the nitrogen atom to which they are bonded, represent an optionally benzo-fused monocyclic or bicyclic ring, which ring may be substituted and may be partially unsaturated,which process comprises reacting in a first stage an alpha-halocarboxylic acid amide of the formula ##STR2## wherein R.sup.1, R.sup.2 and R.sup.3 are identified as above; andHal is chlorine or bromine,with an alkali metal acetate or alkaline earth metal acetate in the presence of a quaternary ammonium salt at a temperature between 20.degree. and 200.degree. C.

Abstract: The present application discloses a method of correcting an imbalance of immune homeostasis caused by cytostatic treatment or radiotherapy by administering to a patient in need of such treatment an effective amount of a novel substituted mercapto acid amide and pharmaceutical compositions containing such novel substituted mercapto acid amides.

Abstract: The disclosure herein relates to a new process for the preparation of N-(halomethyl) acylamides by reacting the corresponding N-(alkoxymethyl) acetamide with a hydrogen halide.

Abstract: 9-deoxy-9A-methylene-isosteres of PGI.sub.2, including processes for their preparation and pharmaceutical and veterinary compositions containing same, are disclosed. The compounds are useful as therapeutic agents, for example as anti-aggregating agents, disaggregating agents, and as vasodilators.

Abstract: Dyestuffs of the formula ##STR1## wherein R.sub.1 represents hydrogen, alkyl or aralkyl,R.sub.2 represents R.sub.1 or aryl,A represents C.sub.2 -C.sub.6 -alkylene,X represents R.sub.2 or acyl,n represents 1-7,m represents 1 or 2 andthe rings B and D can contain customary radicals,with the proviso that n is at least 2 if X represents acyl,give, when mixed with emulsifiers, dyestuff preparations which are in the liquid or dissolved form under dyeing conditions. The use of additional dispersing agents, protective colloids, levelling agents and carriers when dyeing polyester fibres thereby becomes superfluous.
