碱稳定的硼炔[Cp(OC) 2mn =BtBu(IMe)]很容易与单质硫原发生插入反应，生成硼甲酮配合物[Cp(OC) 2mn -E=BtBu(IMe)] （E=S, Se, Te）。以碲为例，硼和碲之间形成了第一个双键，使碲成为与硼形成多重键的最重的主族元素。这种前所未有的相互作用已经在实验和计算上得到了充分的研究。
The base-stabilized borylene [Cp(OC)2 Mn=BtBu(IMe)] readily reacts with elemental chalcogens in an insertion reaction that yields borachalcone complexes [Cp(OC)2 Mn-E=BtBu(IMe)] (E=S, Se, Te). The tellurium example features the first double bond between boron and tellurium, making Te the heaviest main-group element to make multiple bonds with boron. This unprecedented interaction has been fully investigated both experimentally and computationally.
