Carbonyleisen‐assistierte Verknüpfung von Cyclopolyenen mit Acrylsäuremethylester

Abstract: die gleiche n i d~-C~B~-S t r u k t~r~'~~ vor wie fur das Decaethy l-Derivat" l.Bei der Dimerisierung eines aquimolaren Gemischs der 2,3,4-Triethyl-1,5-dimethyl-und Pentaethyl-1,5-dicarbacloso-pentaborane(5) rnit Kalium und lod erhalt man drei gaschromatographisch trennbare'I4l C4B6-Carbaborane (HSC2)4C4B6(CZH5)6 (404)"'l. Bei der gaschromatographischen Trennung[I4] tritt wegen der thermischen Aquilibrierung der vier Geriist-C-Atome nur ein ,,gemischtes" Dimer auf.

“…Iron carbonyl complexes having σ -alkyl− π -allyl coordinated carbon skeleton ligands are obtained in various ways: e.g., by ring-opening complexation of vinylcycloalkanes, nucleophile (e.g. hydride) addition to cationic complexes containing η 5 -ligands, addition of reactive alkenes to diene complexes, cycloadditions to diene complexes possessing an additional conjugated double bond, photolysis of either diene complexes in the presence of acrylate or acrylate complexes in the presence of dienes, and Lewis acid promoted CO insertion into the π -system of diene complexes . Despite these numerous synthetic entries into the class of σ -alkyl− π -allyl coordinated ligands, structural information on such iron carbonyl complexes is sparse and mainly confined to examples in which the σ - coordinated carbon atom carries electron-withdrawing substituents.…”
