- Organotellurium Chemistry. 4. Synthesis and Reactions of Tellurophthalide. The First Alkyltellurenyl Halides
-
The first alkyltellurenyl halides were obtained as isoble but unstable compounds from halogenolysis of tellurophthalide (1c), a compound obtained in almost quantitative yield from 2-(bromomethyl)benzoyl chloride and sodium hydrogen telluride.The structures of the new compounds were confirmed by transformations to a single benzyl tellurocyanate that was independently synthesized.

-
The synthesis of three new basic heterocyclic systems namely, 1H,3H-benzotellurophen-1-one (2-tellurophthalide), 3,4-dihydro-1H-2-benzoselenin-1-one (3,4-dihydro-2-isoselenocoumarin) and 3,4-dihydro-1H-2-benzotellurin-1-one (3,4-dihydro-2-isotellurocoumarin), is reported through the cyclisation of o-(bromoalkyl)benzoyl chlorides.
