Methoxyphenyl 4-methoxyphenylseleno tellurium and 2-carboxyphenyl phenyl iodo-nium betaine heated in 1,2-dichlorobenzene under argon produced 4-methoxyphenyl 2-(4 -methoxyphenylseleno)phenyl tellurium4. 

Benzoylphenyl Tellurium Chloride1 In a dry, 100 m/ flask fitted with a reflux condenser topped with a drying tube are placed 6.5 g (20 mmol) of 2-carboxyphenyl phenyl tellurium, 5 ml (30 mmol) of butyl dichloromethyl ether, and 0.2 g (1.5 mmol) of anhydrous zinc chloride. The mixture is heated on a boiling water bath for 2 h, then diluted with carbon tetrachloride, charcoal is added, and the mixutre is filtered. The filtrate is evaporated to dryness and the residue is recrystallized from benzene/hexane yield 6.3 g (80%) m.p. 113-114°. 

Similarly benzyne, generated by heating 2-carboxyphenyl phenyl iodonium in 1,2-dichlorobenzene, inserted into the Te —Te bond of diaryl ditellurium compounds forming l,2-bis[aryltelluro] benzenes5,6. 

Carboxyphenyl Phenyl Tellurium2 27.2 g (0.2 mol) of 2-aminobcnzoic acid arc dissolved in a mixture of 25 ml of concentrated hydrochloric acid and 70 ml of water. 13.8 g of sodium nitrite dissolved in 20 ml of water are added dropwisc to the stirred amine solution cooled in an icc/walcr bath. Sodium hydrogen carbonate is added until the solution of the diazonium salt is slightly basic. 23 g (56 mmol) of diphenyl ditellurium are dissolved in a mixture of 30 ml of ethanol and 60 ml of THF. To this solution are added 2.3 g (60 mmol) of sodium borohydride dissolved in 33 ml of 1 M aqueous sodium hydroxide. The diazonium salt solution is quickly added to the warm benzenetellurolate solution. 10 ml of 1 M sodium hydroxide are then added and, after the evolution of nitrogen has ceased, the mixture is heated to complete the reaction. The mixture is poured onto ice and diphenyl ditellurium is extracted with benzene. The aqueous phase is acidified with 1 M hydrochloric acid and the product precipitates in analytically pure form yield 28.2 g (43%) m.p. 185° (from toluene). 

Ethoxycarbonylphenyl phenyl tellurium was also obtained from 2-carboxyphenyl phenyl tellurium and diazomethane1. 

Chlorocarbonylphenyl Phenyl Tellurium1 16.2 g (0.05 mol) of 2-carboxyphenyl phenyl tellurium are suspended in 80 ml of dichloromethane and the suspension is cooled to 0°. Then 12 ml of butyl dichloromethyl ether and 0.2 g of anhydrous zinc chloride are added, the mixture is allowed to warm to 20°, and is held at that temperature for 1 h. When all the acid has dissolved, charcoal is added, the mixture is filtered, the filtrate is evaporated, and the resultant product is recrystallized from hexane/benzene yield 11 g (64%) m.p. 89 91°. 

The optically active arsinous acid esters 128-134 and the arsinthious acid ester 135 have been used to prepare optically active tertiary arsines (Table 7). When the arsine sulphide 136 was heated in benzene with n-butyl or -propyl bromide, ethyl bromide was eliminated and there was a reversal in the sign of the rotation, which was attributed to the formation of the inverted n-butyl and n-propyl esters of (p-carboxyphenyl)phenyl-arsinthious acid, 137a and 137b, respectively (equation 18) .

Hexafluoroisopropylidene-unit-containing copoly(ether ketone)s and copoly-(sulfide ketone)s are also synthesized by reacting mixtures of 2,2-bis(4-carboxy-phenyl)-1,1,1,3,3,3-hexafluoropropane (15) and 2,2-bis(4-carboxyphenyl)-propane (16) with diphenyl ether or diphenyl sulfide in PPMA, respectively (Scheme 10).18... 

Crystallinity of these hexafluoroisopropylidene-unit-containing poly(ketone)s is low except for poly(sulfide ketone) (13). The water contact angle for the fluorine-containing poly(ketone) films is high, being 98° for poly(ether ketone) (11), from 2,2-bis(4-carboxyphenyl)-l,l, l,3,3,3-hexafluoropropane(15) and 96° for poly(sulfide ketone) (13) from 15, whereas it is 78° for poly(ether ketone) from 2,2-bis(4-carboxy-phenyl)propane (16) and 74° for the poly(sulfide ketone) from 16. This result indicates that the substitution of isopropylidene units of poly-(ketone)s with hexafluoroisopropylidene units has a remarkable effect on the surface properties of poly(ketone) films. 

Oxidation of dimethyl l-phenyl-2-oxo-l,2-dihydro-llb//-pyrimido[2,l-a]-isoquinoline-3,4-dicarboxylate (64) by potassium permanganate either in acetone or in aqueous potassium hydroxide, followed by treatment with ethereal diazomethane, gave isocarbostyril and methyl oxanilate, respectively (67CB1094). Oxidation of 4-phenyl-2//-pyrimido[2,l-a]isoquinolin-2-one with potassium permanganate in a 1 5 mixture of pyridine and 2 N potassium hydroxide yielded 2-(2-carboxyphenyl)-6-phenylpyrimidin-4(3//)-one (72CB108). 2-Methyl-4//-pyrimido[2,l-a]isoquinolin-4-one and 3,4-dihydro-2//-pyrimido[2,l-a]isoquinoline-2,4-dione with potassium permanganate afforded phthalimide in low yield.

A high concentration of dissolved Ru(bpy)32+ was required for the sensitization, suggesting adsorption of the sensitizer onto the Ti02. tetrakis(4-carboxyphenyl)porphine and tetrakis(4-sulfonic phenyl)porphine sensitizers dissolved in water were also effective for H2 evolution. The presence of a water... 

More recent work117 has brought to light other, surprising, differences between l-(2-carboxy-phenyl- and l-(2-hydroxyphenyl)-formazans and cast some light on the structures of their copper complexes. Like 1,3,5-triphenylformazan, both l-(2-carboxyphenyl)- and l-(2-hydroxyphenyl)-... 

The intensity of the colours of metal complex formazans has, however, found applications in the analytical field for example, it has been reported131 that l-(2-hydroxy-5-sulfophenyl)-3-phenyl-5-(2-carboxyphenyl)formazan (186) can be used for the detection of zinc at a concentration of 1 50000000. 

Copper complexes of the formazan dye series (see Sections 2.10 and 3.11) are another alternative to reactive anthraquinone dyes they produce red to greenish-blue shades. Like triphenodioxazine dyes, copper formazans exhibit high molar extinctions ( e = 25 000 -30 000). These materials are derived from l-(2-hydroxyphe-nyl)-3-phenyl-5-(2-carboxyphenyl)formazan (22), in which all three rings are capable of supporting groups that increase the compound s reactivity and solubility.
