4-phenoxyphenyl

Stamatoff and Wittmann reported a synthesis of a 2-(4-phenoxyphenyl)hexa-duoroisopropanol in the presence of HF and an organic solvent via a Friedel-Crafts reaction, as shown in Scheme 6.29.231 The resulting polymer could be compression molded at 330-350°C. It also exhibited excellent thermostability and mechanical properties.

A poly(arylene ether phenylquinoxaline) of structure 14 was prepared by the aluminum chloride catalyzed reaction of 6,6 -bis[2-(4-phenoxyphenyl)-3-phenylquinoxaline] and isophthaloyl chloride in 1,2-dichloroethane [51]. The polymer had an inherent viscosity of 1.29 dL/g and a Tg of 224 °C. A polymer of the same chemical structure was prepared from the reaction of 3,3, 4,4 -tetraaminobiphenyl with l,3-bis(phenylglyoxalyl-4-phenoxy-4 -benzoyl)-benzene that gave a Tg of 239 °C [16], significantly higher than that prepared by the electrophilic route. In addition, a polymer of the same chemical structure (third polymer in Table 3) prepared via nucleophilic substitution exhibited a Tg of 240 °C.

Figure 9.45 MOF catalysed cyanosilylation reaction - when Ar is phenyl or napthyl the product can pass freely through the pores giving yields of over 90 per cent. When Ar = 4-phenoxyphenyl or biphenyl the yields are below 20 per cent because the molecules do not fit readily within the cavities.

When phenyl tellurium trichloride or 4-phenoxyphenyl tellurium trichloride were reacted with sodium 2-benzoyl-5-methoxyphenoxide in a refluxing mixture of benzene/methanol, compounds were obtained that contained chloride and phenoxide groups3. 

Similarly prepared were 4-phenoxyphenyl phenyl tellurium, and 4-ethoxyphenyl 1-naphthyl tellurium. 

Phenoxyphenyl tellurium tribromide did not react with 1,2-dihydroxybenzene1. The reactions of phenyl tellurium trichloride2 and 4-ethoxyphenyl tellurium trichloride3 with methoxybenzene were carried out at a temperature of 160°. 

Phenoxyphenyl tellurium trichloride and the aryl tellurium tribromides and triiodides did not react at 20°. Upon heating haloacetones were formed1. 

Gradually heating 4-phenoxyphenyl tellurium trichloride from 150° to 210° during 5 h first formed 2-phenoxyphenyl tellurium trichloride and then phenoxatellurin 10,10-dichloride (m.p. 265°) in 33% yield4.
