摘 要：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 PhSCI,PhSeCI or PhTeCI.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.
