The reaction proceeded via generation of 1-iodoalkenylrhenium carbene species by sequential 1,2-iodine and 1,5-hydrogen shifts with readily available precursors under neutral conditions. The reaction mechanism and the reactivity of the generated alkenylcarbene species were also investigated. en-copyright= kn-copyright= en-aut-name=MuraiMasahito en-aut-sei=Murai en-aut-mei=Masahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaiKazuhiko en-aut-sei=Takai en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=anti-markovnikov addition kn-keyword=anti-markovnikov addition en-keyword=silyl enol ethers kn-keyword=silyl enol ethers en-keyword=terminal alkynes kn-keyword=terminal alkynes en-keyword=metal vinylidenes kn-keyword=metal vinylidenes en-keyword=cycloisomerization kn-keyword=cycloisomerization en-keyword=ruthenium kn-keyword=ruthenium en-keyword=complexes kn-keyword=complexes en-keyword=derivatives kn-keyword=derivatives en-keyword=carbene kn-keyword=carbene en-keyword=functionalization kn-keyword=functionalization END
