Rhodium-and Palladium-Catalyzed 1,5-Substitution Reactions of 2-En-4-yne Acetates and Carbonates with Organoboronic Acids. -The reaction of (E)-and (Z)-enyne carbonates and (Z)-enyne acetates allows convenient access to (E)-configurated vinylallenes. Starting from (E)-enyne acetates, however, vinylallenes are not available. The reaction of optically active enynes proceeds with racemization. -(UECUENCUE, M.; KARAKUS, E.; KUS, M.; AKPINAR, G.
