Iron( ii )-induced cycloisomerization of alkynes via “non-vinylidene” pathways for iron( ii )-indolizine and -indolizinone complexes

Iron( ii )-induced cycloisomerization of alkynes via “non-vinylidene” pathways for iron( ii )-indolizine and -indolizinone complexes

Reactions between pyridine-functionalized alkynes and an Fe( ii ) precursor supported by 2,5,8-trithia[9](2,9)-1,10-phenanthrolinophane afforded the first Fe( ii )-indolizine and -indolizinone complexes. Structural analysis and theoretical calculations revealed the existence of unconventional “non-v...

Zusammenfassung:Reactions between pyridine-functionalized alkynes and an Fe( ii ) precursor supported by 2,5,8-trithia[9](2,9)-1,10-phenanthrolinophane afforded the first Fe( ii )-indolizine and -indolizinone complexes. Structural analysis and theoretical calculations revealed the existence of unconventional “non-vinylidene” pathways and challenged the generality of vinylidene intermediacy in Fe( ii )-induced alkyne transformations.
