Oxanilide UV stabilisers of the general form ArNH(C=0)(C=0) NHAr have been known for some time in symmetric [89] and asymmetric [90] forms. Both are available commercially from Clariant as Sanduvor EPU and VSU respectively. Also patented were bis-oxalic acid diamides [91] of basic structure ArNH(C=0)(C=0) NH-R-NH(C=0)(C=0)NHAr. [Pg.209]

Confirmatory evidence for streptosonic acid diamide existing as structure XXI was obtained by a study of the oxidation products of streptosonic acid monolactone (XXIII). When this compound was oxidized with two moles of periodic acid, two of the cleavage products were identified as glyoxylic acid (XXIV) and oxalic acid (XXV). The suggested course of the oxidation, on the basis of structure XXIII, is shown... [Pg.362]

Dithiooxamide Dithioxamide EINECS 201-203-9 Ethanedithioamide HSDB 5230 Hydrorubeanic acid NSC 1893 Oxaldiimidic acid, dithio- Oxalic acid, dithiono-, diamide Oxamkfe, dithio- Rubean Rubeane Rubeanic acid RVK USAF B-43 USAF EK-4394 USAF MK-6. The amide of dithiooxalic aoid, a chelating agent, especially for copper, cobalt and nickel. Also used to stabilize ascorbic acid solutions. Red crystals mp = 170 (dec) X.m = 312 nm (s = 10300 MeOH) slightly soluble in H2O, EtOH, insoluble in organic solvents. [Pg.250]

Tertiary alcohols can be conveniently deoxygenated in high yields through thiohydroxamic-O-esters. In practice, an oxalic acid half ester is prepared and decomposed in the presence of t-butylthiol or 1,1-diethylpropanethiol under radical conditions (equation 27). Diethyl phosphates and iV,A,N, AT -tetramethylphosphoro-diamidates of alcohols are readily reduced by lithium-ethylamine solutions. The method works well with both secondary and tertiary alcohols, the latter shown by the conversion of 1-adamantanol to adamantane (equation 28) °. [Pg.567]

Rubeanic acid, the diamide of dithio-oxalic acid, presents an equilibrium mixture with its tuatomeric (aci-) di-imido form as outlined on page 406. The aci-form combines with nickel, cobalt, and copper ions to give colored water-insoluble polynuclear coordination polymers. [Pg.329]
