Recently, the decomposition of N-sulfonyloxy-AAF under aqueous conditions has been further examined and appears to be consistent with this overall mechanism (50). That is, the major products appear to be 1- and 3-sulfonyloxy-AAF with small amounts of AAF, 4-hydroxy-AAF, and a dimer formed by addition of the electrophile onto the aromatic ring of another AAF molecule (51). Furthermore, the relative yields of AAF could be increased by addition of the reducing agent, ascorbic acid (52). 

A useful copper physical developer consists of a mixture of a copper(II) salt [Cu(N03)J, an amine such as triethanolamine to make the system basic as well as to sequester Cu11, and a reducing agent (ascorbic acid). It can be used to develop Cu, Ag, Pd, Pt and Au nuclei.180... 

Fig. 21. A redox-driven translocation based on the Cu(II)/Cu(I) change. The Cu(II) ion stays in the tetramine compartment of the heteroditopic ligand 13, whereas the Cu(I) ion prefers to occupy the bis(2, 2 -bipyridine) compartment. The very fast translocation of the copper center between the two compartments can be induced chemically (reducing agent ascorbic acid oxidizing agent hydrogen peroxide)...

More traditional O2 oxidation experiments were attempted with the vaulted iron and manganese complexes in several solvents with many of the reducing agents (ascorbic acid, sodium ascorbate, thiols, borohydride, and amalgamated zinc) that have been used elsewhere in work with porphyrins and their derivatives. " The more promising systems are mentioned here. Various thiols, such as thioglycol ethyl ester and P-mercaptoethanol, were... 

Not surprisingly, the reducing agent ascorbic acid (vitamin C) has certain chemical features common with the reducing sugar glucose. Briefly, observations made on the effect of ascorbic acid supplementation in diabetic individuals, the prooxidant ability of ascorbic acid in vitro, and the ability of ascorbic acid to modify proteins are of interest in the context of the development of diabetic complications. 

Prepared spherical silver nanoparticles are then added to a solution containing more silver salt, a weak reducing agent (ascorbic acid) and a surfactant (CTAB). Ascorbic acid is a weak reducing agent and cannot reduce the silver salt in the present of the micelle without the presence of seeds [301] ...
