The reaction of 4-X-5-alkylthio-3H-1,2-dithiole-3-thione (1) with Fischer carbene complexes (2) gives, as a main product, cyclohexa dithiine derivatives due to insertion of the carbene ligand into the C3 C4 bond of the heterocycle. The reaction takes place with 1 where the alkyl substituents in posi
## Abstract The first examples of insertion of a CC bond of an alkyne into a C~carbene~C~__α__~ single bond of a carbene complex (CC~__α__~ insertion) are reported. (__prim‐__Alkyl)carbene complexes [(OC)~5~MC(OEt)CH~2~R] (1 a–f; M=Cr, W; R=__n__Pr, C~7~H~7~, Ph) undergo CC~__α__~ insertion of
