Ringöffnende Carbonylierung des Spiro[2.4]hepta‐4,6‐dien‐Systems mit Tetracarbonylnickel

Abstract: Ring Opening and Carbonylation of the Spiro[2.41hepta-4,6-diene System with TetracarbonylnickelNi(CO),-induced opening of the three-membered ring in spiro[2.4]hepta-4,6-diene (1) is directed by methyl and vinyl substituents. While a methyl group in 1-position hinders the opening of the adjacent three-membered ring CC bond, a vinyl group enhances the opening of this bond. Besides bridged o-alkyl-and o-acyl-x-cyclopentadienyl complexes 2, 5, 6, 9, and 10, dinuclear systems 3 and 7 are also formed, containing a p… Show more

“…The reversibility of methyl transfer between the ruthenium center and the π-allyl ligand is similar in many regards to that seen by Green, Eilbracht, Crabtree, , and most recently Wolczanski . In 1974, Benfield and Green reported the reversible transfer of an ethyl group between the Cp ligand and the metal in Cp 2 MoEtCl .…”
