Cleavage of the SnSn Multiple Bond in a Distannyne by Cyclooctatetraene: Formation of the π‐Bound Inverse Sandwich Complex [(Ar′Sn)₂(μ₂‐η²:η³‐cot)]

Abstract

Wenn ein Distannin Cyclooctatetraen aktiviert, kommt es zur vollständigen Spaltung der SnSn‐Bindung und zur Bildung eines inversen Sandwich‐Komplexes mit einem π‐gebundenen aromatischen planaren C8H8‐Ring (siehe Schema; Ar′ = C6H3‐2,6‐(C6H3‐2,6‐iPr2)2).

Tuning Main Group Redox Chemistry through Steric Loading: Subvalent Group 13 Metal Complexes of Carbazolyl Ligands

“…[4] Such species have been of interest not only from a fundamental structure/bonding perspective (e.g. novel bond orders or very low coordination numbers), [3,4] but also from the viewpoint of developing and controlling patterns of reactivity stemming from electronic and coordinative unsaturation (e.g. in the activation of dihydrogen).…”

“…[1,2] In particular, phenyl ligands bearing bulky alkyl or aryl substituents in the 2-and 6-positions (I; Scheme 1), which were pioneered principally for main-group-metal systems, [3] have more recently been exploited in the synthesis of landmark multiplybonded transition-metal compounds, such as Powers CrÀCr quintuple bond. [4] Such species have been of interest not only from a fundamental structure/bonding perspective (e.g.…”
