Phenols and derivatives are the main aromatic compounds of plants, whose structural formulas contain at least one benzene ring. They serve as odors, fungicidals, or germination inhibitors. Coumarins are especially common in grasses, orchids, citrus fruits, and legumes. Plants containing phenols with anticancer properties include the following ...

The Influence of the Matrix Precursor. The first requirement for a suitable matrix precursor is high carbon yield, which must be achievable under simple pyrolysis conditions. Figure 14 (left-hand side) shows weight loss as a function of pyrolysis temperature for several matrix precursors practical precursors that are commercially available include coal-tar and petroleum pitches, phenolic resins, polyimides, and the para-polyphenyleneacetylene resin Hercules HA 43 (35,36) The structural formulas of some polymer binders are shown in Figure 15. 

The compounds of structure 9 were obtained by condensing a phenol of formula 10 with a compound of formula 11 and following saponification or in the special case of Rj = R, = CH3 with chloroform and acetone in the presence of potassium hydroxide377. The compounds 11 were commercially available or readily prepared by a-halogenation of the corresponding esters 12. 

On this evidence Schopf was unable to advance a structural formula for flavothebaone. It was, however, clear that the a. /3-unsaturated ketone system is in conjugation with one of the phenolic groups as, though the sodium salt of flavothebaone is red, the sodium salt of dihydroflavothebaone is colourless [2],...

Dubach and Mehta (1963) define humic substances as a series of predominantly aromatic-phenolic polymers, whose acidity is mainly due to carboxyl groups, and which are free of carbohydrates and probably of nitrogen. They state that the presence of quinonic structures cannot be confirmed or excluded. They are of the opinion that there are ether linkages between the aromatic monomers, but humic substances are too nonhomogeneous to justify an attempt to write a structural formula for them, as was done in the past. The humic substances constitute over 50% of the organic matter of mineral soils. At the present time few workers would have any doubt that these substances contain nitrogen.

An important goal of antioxidant research has been to provide poly-phenols of high molecular weight and low volatility. Most of the commercial sterically hindered phenols have molecular weights in the range 300-600 and above 600. Figure 1.41 depicts structural formulas [45] of the important sterically hindered phenols used as antioxidants. 

With these results in mind, we have prepared and evaluated a number of catecholate type ligands. The structural formulas for these ligands are shown in Figure 4. Like enterobactin, all these ligands can bind ferric ion via six phenolic oxygens from three catechol groups. Unlike enterobactin, they are also hydrolytically stable over normal pH ranges. 

Phenolic resin precursors are formed by a condensation reaction and water is formed as a by-product. The structural formula is ... 

As the name implies, these resins are derived from phenol and formaldehyde. The structural formula is shown in Figure 3.7. Phenol-formaldehyde is cross-linked phenolic resin and, in general, has approximately the same basic physical and mechanical properties as other phenolic resins. However, it does not have the impact resistance of the polyesters or epoxies.
