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.
