Skeletal reorganization of enynes into 1-vinylcycloalkenes in ionic liquids.
The skeletal reorganization of enynes catalyzed by transition metal chlorides, such as PtCl(2), [RuCl(2)(CO)(3)](2), [RhCl(CO)(2)](2), and AuCl(3), in ionic liquids proceeds under milder conditions (at lower reaction temperatures and for shorter reaction times) than those needed for ordinary solvents. The products produced by the skeletal reorganization of enynes were easily removed from the catalyst by a simple extraction with Et(2)O or distillation. The PtCl(2) can be reused up to five times.
