Unsupported Mg-Alkene Bonding.

ABSTRACT: The first intermolecular early main group metal-alkene complexes were isolated. This was enabled by using highly Lewis acidic Mg centers in the Lewis base-free cations (^Me BDI)Mg⁺ and (^tBu BDI)Mg⁺ with B(C₆ F₅ )₄ ^- counterions (^Me BDI=CH[C(CH₃ )N(DIPP)]₂ , ^tBu BDI=CH[C(tBu)N(DIPP)]₂ , DIPP=2,6-diisopropylphenyl). Coordination complexes with various mono- and bis-alkene ligands, typically used in transition metal chemistry, were structurally characterized for 1,3-divinyltetramethyldisiloxane, 1,5-cyclooctadiene, cyclooctene, 1,3,5-cycloheptatriene, 2,3-dimethylbuta-1,3-diene, and 2-ethyl-1-butene. In all cases, asymmetric Mg-alkene bonding with a sho
