Reaction of 2-(methylseleno)- and 2-(phenylseleno)benzoic acids and their derivatives with tert-butyl hydroperoxide. Neighboring selenium participation and facile formation of cyclic selenuranes and a selenurane oxide
A facile formation of cyclic selenuranes and a cyclic selenurane oxide in the reaction of 2-methylseleno- and 2-phenylselenobenzoic acids and their derivatives with t-butyl hydroperoxide
The reaction of 2-methylselenobenzoic acid with 1,1′-carbonyldiimidazole followed by addition of t-butylhydroperoxide gave cyclic selenuranes and , suggesting the intramolecular insertion of the neighboring selenium atom into the OO bond of t-butyl 2-methylselenoperoxybenzoate. In the reaction of 2-phenylselenobenzoyl chloride with t-butylhydroperoxide, cyclic selenurane and the oxide were obtained
