Abstract

A λ3,σ2 SbC double bond that is not part of a cyclic electron system is present in the distibabutadiene 1, which is formed in the reaction of (2,4,6-C6H2tBu3)COCl with Li[Sb(SiMe3)2(dme)]. The X-ray crystal structure analysis of 1 indicates a degree of double-bond delocalization that, in addition to steric bulk, stabilizes this unusual molecule.
