Abstract: Novel imide carboxylates, O-carboxylates thereof, and amide carboxylates are useful as intermediates for preparation of sequestrant compounds.

Abstract: Ketoalkanesulfenylcarbamoyl and ketoalkanethiosulfenylcarbamoyl halides are useful intermediates in the preparation of pesticidally active carbamates.

Abstract: Selected organic peroxides are converted to the corresponding alcohols when contacted with a triorganophosphine in a reaction medium comprising water and an organic solvent miscible with water. In one embodiment, diene polyperoxides are converted to the novel diols.

Abstract: Process for the manufacture of a heterocyclic compound of the formula I ##STR1## in which Y denotes a --CN, --COOR' or ##STR2## group, in which R' can be an optionally substituted alkyl or aryl radical and R" and R"' independently of one another can have the same meaning as R' or can be hydrogen or, conjointly with the nitrogen atom, can form a heterocyclic 5-membered or 6-membered ring and X denotes a --S-- or --O-- atom or a --NR"-- group and the ring A can carry non-ionic substituents or optionally substituted fused rings, wherein a nitrile of the formula IInc -- ch.sub.2 -- y (ii)is reacted, in organic solvents, with a lower alcohol of the formula IIIr -- oh (iii)using a molar ratio of nitrile to alcohol of 1:0.9 to 1:1.2, in the presence of an anhydrous strong acid at temperatures of -10.degree. to +40.degree.

Abstract: Novel imide carboxylates, O-carboxylates thereof, and amide carboxylates are useful as intermediates for preparation of sequestrant compounds.

Abstract: 1,1-Bis(perfluoroalkylsulfonyl)propanes substituted in the three position by two to three electron-withdrawing groups, particularly perfluoroalkylsulfonyl, carboxyl, carboalkoxy or cyano are catalysts for the polymerization of aromatic epoxy resins.
