From 2-Phenoxyphenyl Tellurium Trichlorides

When 2-phenoxyphenyl tellurium trichlorides were heated at 200 240°, hydrogen chloride evolved and phenoxytellurin 10,10-dichlorides were formed.  [Pg.848]

2-MethylphenoxatelIurin 10,10-Dichloride 16.8 g (40 mmol) of 2-(4-methylphenoxy)-phenyl tefluriiun trichloride are placed in a large test-tube and heated at 200-240° in an oil bath for 0.5 h with occasional stirring. The deep red solid is cooled, ground, and rccrystallized from acetone to give pale yellow plates yield 12.2 g (80%) m.p. 275 . [Pg.848]

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% yields [Pg.848]

Crude yield mixed with 2,8-dichlorophenoxatellurin 10,10-dichloride. Impure product. [Pg.849]


A more general method of preparation of various 10,10-dichlorophen-oxatellurines comprises intramolecular electrophilic cyclization of 2-phenoxyphenyl tellurium trichlorides, which are readily accessible from the corresponding arylmercury chlorides or aryltrimethylsilanes (83MI2). [Pg.93]
