Dihydroxybenzene (hydroquinone), 2-methyl-, 2,3-dimethyl-, and 2-t-butyl-hydroquinones, 1,2-dihydroxybenzene (catechol), ( 1 g each) methanol NaOH pellets. 

The role of Domain II in the recognition process was probed by using a rhodium dimethyl amide of 2,3-dihydroxybenzene (DMB) as a catechol ligand, with one more carbonyl ligand than in the tris(catecholato)-rhodium(III) complex. Remarkably, this molecule shows substantially the same inhibition of en-terobactin-mediated iron uptake in E. coli as does rhodium MECAM itself. Thus, in addition to the iron-catechol portion of the molecule, the carbonyl groups... 

Bowen [148] obtained crystalline acrylic monomers, thus making it possible to purify them. By the reaction of 2-hydroxyethyl methacrylate with the three isomers of benzene dicarboxylic acid—phthalic, isophthalic, and terephthalic acid—adequate esters are obtained mixed in various proportions, these make an eutectic ternary mixture that can play the role of the organic phase in DARs. The only shortcoming of these monomers is that they show a tendency to acquire color in the presence of the polymerization accelerators (N,N-dimethyl-p-toluidine). Isomer dimethacrylates (o-, m-, and p-)bis(hydroxyethyl)-dihydroxybenzen-...
