Organyltellurium trichlorides from tellurium tetrachloride and organic substrates

1 Organyltellurium trichlorides from tellurium tetrachloride and organic substrates [Pg.47]

1 From tellurium tetrachloride and ketones and carboxylic anhydrides [Pg.47]

Reactions involving the attack of a nucleophilic carbon atom activated by an a-carbonyl group at the electrophilic tellurium atom of tellurium tetrachloride belong to the oldest methods of preparative organic tellurium chemistry. [Pg.47]

Depending on the structure of the ketone, different regiosubstituted trichlorides are obtained, in addition to the corresponding dichlorides. [Pg.47]

Acetic and propionic anhydrides furnish compound of type RCH(TeCl3)C02H (R=H, Me) [Pg.48]
