Ruthenium-Catalyzed [1,n]-Metallotropic Shift (n = 3, 5) of Alkynyl Carbene Complex Intermediates

Ruthenium-Catalyzed [1,n]-Metallotropic Shift (n = 3, 5) of Alkynyl Carbene Complex Intermediates

The ruthenium-catalyzed isomerization of diynes and triynes involving propargyl carboxylate moieties affords dienynes and dienediynes, respectively. The [1,n]-metallotropic shift (n = 3, 5) (carbene walk) of in situ generated alkynyl carbene complexes has been proposed for the catalytic isomerizatio...

Zusammenfassung:The ruthenium-catalyzed isomerization of diynes and triynes involving propargyl carboxylate moieties affords dienynes and dienediynes, respectively. The [1,n]-metallotropic shift (n = 3, 5) (carbene walk) of in situ generated alkynyl carbene complexes has been proposed for the catalytic isomerization reaction.
