Dihydrogen and Ethylene Activation by a Sterically Distorted Distibene

Abstract
Abstract Herein, we report the synthesis of a sterically distorted distibene ( [4] 2 ) and its transition‐metal‐like reactivity towards two fundamental feedstock chemicals: H 2 and ethylene. Although [4] 2 exhibits an unusually long Sb=Sb distance and noticeable backbone distortion in the solid state, NMR data suggest that [4] 2 remains predominantly as a dimer in solution, even at high temperatures. However, it was proposed that the elusive reactivity of [4] 2 toward H 2 and ethylene results from reversible dissociation of [4] 2 into the transient stibinidene ( [4] ), which could be observed by NMR spectroscopic techniques.
