ABSTRACT
Herein, we report the synthesis of a sterically distorted distibene ([4]2 ) and its transition-metal-like reactivity towards two fundamental feedstock chemicals H2 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 H2 and ethylene results from reversible dissociation of [4]2 into the transient stibinidene ([4]), which could be observed by NMR spectroscopic techniques.
