Abstract
Read the full textAbout AbstractSubstitutes you can rely on: Mesoionic carbenes (MICs) are not always stable. However, the acyclic ethynylcarbamodithioate 2 formed (instead of the corresponding MIC) by deprotonation of dithiolium salt 1 underwent cyclization to its precursor under acidic conditions and reacted with a variety of transition?metal centers to yield robust MIC complexes 3; (see scheme; Tipp=2,4,6?triisopropylphenyl).
