本文报道了从锰硼络合物与硫属元素反应中分离出BE_2杂环化合物（E = Te，Se，S）。BTe 2和BSe 2环--分别是硼化二碲环和硼化二硒环--是基于重硫族元素的二环氧乙烷的第一个类似物。虽然BTe 2单元仍然被发现与锰配位结合，但Se和S类似物以其游离形式分离。所有的杂环已被证明转移硫族原子，允许新的borachalcone和它们的二聚产物的隔离。
The isolation of BE2 heterocycles (E = Te, Se, S) from the reaction of a manganese borylene complex with elemental chalcogens is reported. The BTe2 and BSe2 cycles-a boraditellurirane and a boradiselenirane, respectively-are the first analogs of dioxiranes based on heavy chalcogens. While the BTe2 unit is still found datively bound to manganese, the Se and S analogs were isolated in their free forms. All heterocycles have been shown to transfer a chalcogen atom, allowing for the isolation of novel borachalcones and their dimerization products.
