Synthesis of chalcogeno lactones. II. 3, 4-dihydro-1 H-2-benzothiin-3-one, 3,4-dihydro-1H-2-benzoselenin-3-one and 3,4-dihydro-1H-2-benzotellurin-3-one
[en] The synthesis of 3, 4-dihydro-1H-benzothiin-3-one and its selenium and tellurium analogs is reported from o-bromomethylphenylacetyl chloride and sodium hydrogen chalcogenates, via phase-transfer catalysis.
