Abstract: Salts of alkyl- and/or alkenylsuccinic acid half-amides The invention relates to salts of alkyl- and alkenylsuccinic acid half-amides of the formulae and/or ( Ia) ( Ib) in which R1 is C6-C100-alkyl or C6-C100-alkenyl (straight-chain or branched), R2 is a deoxysaccharide radical which is derived from mono-, di- or oligosaccharides, R3 is hydrogen, C1-C6-alkyl or R2, and X+ is a proton, an alkali metal ion, the equivalent of an alkaline earth metal ion, or an ammonium ion of the formula N+HR4R5R6 (II) or of the formula N+HR2R3R4 (III), in which R4, R5 and R6 independently of one another are hydrogen, C1-C20-alkyl, a hydroxyl group, C1-C6-hydroxyalkyl or C3-C6-polyhydroxyalkyl and R2, R3 and R4 have the abovementioned meanings. The invention furthermore relates to a process for the preparation of the salts of alkyl- and/or alkenylsuccinic acid half-amides, which comprises reacting an alkyland/or alkenylsuccinic acid anhydride with carbohydrates containing amino groups in the presence of basic compounds.

Abstract: Compounds of the formula I … … are described in which L denotes H or CO-(R )n(CX3)m, M denotes alkylene, alkenylene or arylene, Q denotes S, Se, O, dialkylmethylene, alken-1,2-ylene, 1,2-phenylene or N-R, where M + Q together form 3 or 4 ring members, R denotes alkyl, aralkyl or alkoxyalkyl, R denotes an aromatic group, and X denotes Cl, Br or I and n = 0 and m = 1 or n = 1 and m = 1 or 2. The compounds eliminate HX on irradiation and form radicals. They are therefore highly active acid donors and radical initiators for photochemical processes.
