英文摘要CO-promoted sulfuration with elemental sulfur and selenylation with elemental selenium of Fischer biscarbene complexes of chromium have been achieved by means of in-situ-generated SCO and SeCO, efficiently affording thio- and selenocarboxylates. Intramolecular reactivity inversion of the chromium carbene carbon bonds (Cr=C) in an alkoxy-alkoxy biscarbene complex was realized by replacement of the alkoxy group bonded to the more reactive Cr=C carbon atom with an amino moiety. A strained cyclobutenyl ring activates the aminocarbene carbon bond, which thus undergoes oxidation, sulfuration, and selenylation under mild conditions. Demetalation of alkynyl, alkenyl, and alkyl Fischer monocarbene complexes was also investigated by the same method, from which selenium- or sulfur-insertion complexes and seleno- and thiocarboxylates were obtained.
