Photoformylation (the photo-Riemer-Tiemann reaction) of phenols (phenol, 2-methyl, 3-methyl, 4-methyl, 4-chloro, 4-bromo, 4-nitro and 4-phenyl phenol) has also been studied by irradiation in chloroform with KOH and pyridine. The yields reported are variable but formylation is reported only to occur in the 2-position ° °. This process involves the addition to phenol of radicals produced from chloroform. An electron transfer mechanism (transfer from excited state phenol to chloroform) is thought to be involved. The radical ion pair eliminates HCl and combination affords the products 232-234 (Scheme 26). The principal product is the ether and this undergoes partial conversion to the formate. The other products formed in low yield are the aldehydes . In another application of the photo-Riemer-Tiemann reaction, this time in cyclodextrin, the phenols can be converted into 4-hydroxybenzaldehydes with high selectivity . ...

The propenoidic phenols, E-methyl ferulate (1), E-4-hydroxycinnamic acid me yl ester (4) and E-3-chloro-4-hydroxycinnamic acid methyl ester (7), can be catalytically oxidized with dioxygen in the presence of [Co(salen)] (Figure 8) . The yields depend on the solvent and the phenyl substituents. EPR and electronic spectra suggest the involvement of a coordinated o-benzosemiquinone type radical as the active intermediate. 

The second order nature of quaternization reactions in our system was confirmed by rate studies on model compounds. Although benzyl chloride is usually selected as the model for chloro-methylated polymers , we chose to synthesize a difunctional model that would be sensitive to neighboring group effects. Condensation of 4-chlorophenyl phenyl sulfone with the disodlum salt of bis-phenol-A yielded an excellent model for the polysulfone segment, Quantitative chloromethylation of with a chloromethyl methyl ether/ methyl acetate mixture in the presence of stannic chloride afforded the corresponding bischloromethyl adduct,...

Chloro-6-methyl-l,5-naphthyridine reacts readily with methano-lic methoxide (65°, 7 hr, 75% yield), but more vigorous conditions (180°, 2-7 hrs, 30-85% yield) were used for various aminations. The 4-chlorodiazanaphthalene reacted with a sec-alkylamine under less vigorous conditions (95%, 36 hr, 85% yield) and with ammonia-phenol (180°, 3 hr, 50% yield) gave the phenoxy derivative which was also alkylaminated (200°, 3 hr, 90% yield).The 3-bromo and 3-bromo-2-ethoxy derivatives of428 were aminated with copper sulfate and concentrated ammonia (170°, 40 hr, 75% yield).

A subsequent study, using clearly homogeneous conditions, of the dedeutera-tion of [2-2H]-4-nitro-, -chloro-, and -methyl-phenols by aqueous sulphuric acid showed that the rate coefficients clearly increased with increasing acidity (Table 120) and plots of log rate coefficient versus the acidity function — H0 were linear,... 

C12 to C20, primarily Ci6 to ( is), used as surface lubricants in the manufacture of food-contact articles. The method, which uses ethyl palmitate (Eastman Chemicals No. 1575 Red Label) as an internal standard, has been validated at 200 ppm total FAME [185]. Other FAME standards (methyl palmitate, methyl stearate, methyl oleate, methyl linoleate and methyl linolenate) are available (Applied Science Laboratories) [116], Worked out examples of additive determinations are given in the Food Additives Analytical Manual [116], which also describes a great many of indirect food additives, such as BHA, BHT, TBHQ, l-chloro-2-propanol, DLTDP, fatty acid methyl esters, w-heptyl-p-hydroxybenzoate, propyl-gallate, sodium benzoate, sodium stearoyl-2-lactylate, sorbitol and phenolic antioxidants. EPA methods 606 and 8060 describe the CGC separation of phthalate esters (direct injection) (cf. Figure 4.2). 

As is apparent from Fig. 1, the dianions of monoalkyl phosphates normally resist hydrolysis. However, for leaving groups whose conjugate acids exhibit a pKa < 5 in water, hydrolysis of the dianion becomes faster than that of the monoanion. Fig. 2 shows a pH profile characteristic of this situation. Whereas the hydrolysis rate of 2,4,6-trichlorophenyl phosphate (pKa of the phenol 6.1) still shows the typical monoanion preference as seen for methyl phosphates (Fig. 1), the dianion of 2,4-dinitrophenyl phosphate (pKa of the phenol 4.09) is hydrolyzed far faster than the monoanion 2-chloro-4-nitrophenyl phosphate represents an intermediate case (pKa of the phenol 5.45)6S). 

A novel series of a-substituted phenoxy-A-methyl-l,2,3-thiadiazole acetamides 51 is obtained through nucleophilic substitution of the chloro compound 50 with several phenols, and the resultant phenoxy derivatives were evaluated against heptatitis B vims (HBV) (see Section 5.07.12) (Equation 13) <2003JHC925>. 

Chau and Terry [146] reported the formation of penta-fluorobenzyl derivatives of ten herbicidal acids including 4-chloro-2-methyl-phenoxy acetic acid [145]. They found that 5h was an optimum reaction time at room temperature with pentafluorobenzyl bromide in the presence of potassium carbonate solution. Agemian and Chau [147] studied the residue analysis of 4-chloro-2-methyl phenoxy acetic acid and 4-chloro-2-methyl phenoxy butyric acid from water samples by making the pentafluorobenzyl derivatives. Bromination [148], nitrification [149] and esterification with halogenated alcohol [145] have also been used to study the residue analysis of 4-chloro-2-methyl phenoxy acetic acid and 4-chloro-2-methyl phenoxybutyric acid. Recently pentafluorobenzyl derivatives of phenols and carboxylic acids were prepared for detection by electron capture at very low levels [150, 151]. Pentafluorobenzyl bromide has also been used for the analytical determination of organophosphorus pesticides [152],...
