Herein,　we　report　a　distinctive　and　marvelous　dual-migration　of　alkynyl　tetracoordinate　borons　activated　by　both　hydrochloric　acid　(HCl)　and　N-chlorosuccinimide　(NCS),　which　is　significantly　different　from　conventional　migration　modes　under　basic　conditions.　In　this　protocol,　HCl,　as　the　first　electrophile,　activates　the　C　equivalent　to　C　bond,　triggering　the　first　1,2-aryl　migration.　Subsequently,　NCS　promotes　a　secondary　metallate　shift,　enabling　the　construction　of　polysubstituted　alkenes.　Notably,　this　process　can　work　well　under　mild　conditions,　exhibits　high　efficiency,　and　provides　valuable　products.　This　transformation　reveals　that　Zweifel　olefination　is　not　just　limited　to　traditional　basic　conditions,　it　can　proceed　smoothly　under　acidic　conditions　as　well,　which　greatly　expands　the　scope　of　this　well-known　olefination　reaction.
