Hexakis(but‐3‐ynyl)benzene

Abstract

The twelvefold dehydrobromination provides the title compound 1 in a straightforward, easily reproducible synthesis. In the solid state 1 displays a well-defined structure with Ci symmetry, in which four of the the six branches assume trans and two assume gauche arrangements. Compound 1, which can be stannylated, deprotonated, and complexed, should be a useful intermediate in the preparation of dendritic structures.
