Benzamide Derivatives

Reactivity studies of strong organic acids based on the replacement of one or both of the oxygens in benzoic acids with the trifluoromethanesulfonamide group are reported. Novel derivatives of these types of acids were synthesized in good yields. The generated N-triflylbenzamides were further functionalized through cross-coupling and nucleophilic aromatic substitution reactions. All compounds were stable in dilute aqueous solutions. Studies of stability under acidic and basic conditions are also reported.

AbstractRadiation chemistry and photocatalysis are introduced as complementary methods for the study of the radical- and redox-induced degradation of organic substrates. Particular focus is devoted on the reductive and oxidative formation and destruction of halogenated organic acids, as intermediates in the degradation of halo- genated hydrocarbons, in dilute aqueous solutions. The specific aim of this comparative essay is to point out the fundamental similarities between a radiation chemical and photocatalytical approach but, at the same time, to demonstrate that and why significant differences may, nevertheless, be observed. The examples presented and discussed are concerned with (i) the oxidatively and reductively induced degradation of 1,1,1-trichloroethane to organic acids, (ii) corresponding experiments on the degradation of trifluoro-, trichloro- and tribromoacetic acid, (iii) peculiarities of the degradation processes in the absence of oxygen, and (iv) the importance of the cross­termination reaction between halogenated peroxyl radicals and superoxide, O

The reactions of sorbitol, mannitol, adonitol, dulcitol, glucose and glycerol with H3AsO4, H3AsO3, H3BO3 and GeO2 acids in dilute aqueous solutions were studied by potentiometric neutralization titrations. The formation of the following chelates was demonstrated: As(V)L3-, As(III)L(OH)2-, HAs(III)L(OH)2, BL2-, GeL2(OH)- and GeL32- and the equilibrium constants for their formation were found. Conditions for formation of these chelates of organic oligohydroxy compounds are discussed.
