Through Reactions of Hydroxy Groups

Aryl 2,4-dihydroxyphenyl tellurium dichlorides kept in acetic anhydride in the presence of a drop of concentrated hydrochloric acid formed aryl 2,4-diacetoxyphenyl tellurium dichlorides  [Pg.566]

4-Diacetoxyphenyl 4-Methoxyphenyl Tellurium Dichlorideb To 0.21 g (0.5 mmol) of 2,4-dihydroxyphenyl 4-methoxyphenyl tellurium dichloride are added 5 ml of acetic anhydride followed by 1 drop of concentrated hydrochloric acid. The mixture is gently shaken until it is homogeneous and is then allowed to stand at 20° for 24 h. The mixture is then cooled in an ice bath, water is added dropwise to the stirred mixture, the precipitated product is filtered off, and recrystallized from benzene/petroleum ether (b.p. 50- 70°) yield 0.22 g (88%) m.p. 167° [Pg.566]
