Chalcogenirenium cations, featuring an unsaturated three-membered organic ring, are limited but known to be synthesizable from alkynes with bulky electron-donating groups. Metalla-chalcogenirenium compounds have been synthesized as stable compounds through the reactions of a cyclic metal-carbyne complex—metallapentalyne with PhSCl, PhSeCl or PhTeCl. As a result of the high strain in the three-membered metallacycles, the metalla-chalcogenirenium cations react readily with the base or chloride ions. These reactions furnish a series of unprecedented chalcogenirenium cations with intact M=C bonds. The intrinsic stabilization effect of aromaticity is further elucidated by density functional calculations.

金属硫族钌化合物的合成，表征和反应性†

具有不饱和三元有机环的硫属元素鎓阳离子是有限的，但已知可从具有大量给电子基团的炔烃中合成。金属-硫属元素鎓化合物已通过环状金属-碳炔配合物金属金属戊烯与PhSCl，PhSeCl或PhTeCl的反应合成为稳定化合物。由于三元金属环中的高应变，金属硫属元素鎓阳离子容易与碱或氯离子反应。这些反应提供了一系列空前的具有完整的M = C键的硫属钌鎓阳离子。密度函数计算进一步阐明了芳香性的内在稳定作用。
