“…The C1-Br1 bond length in the present structure is 1.976 (5) A ˚, close to the mean of 1.950 (2) A ˚found for 11000 aliphatic C-Br bond lengths in the database. The only other sulfone in the database with a phenyl group on each �-C atom and a bromine atom on at least one of the �-C atoms is entry WAVWOJ (Corfield, 2022). That analysis resulted from a similar collaboration with the Bordwell laboratory.…”

The title compound, C16H17BrO2S, crystallizes as the erythro (RR/SS) isomer of a pair of sulfones that were diastereomeric due to chirality of the α-carbon atoms on the sulfone sulfur atom. The structural analysis was pivotal in showing that the 1,3 elimination reactions of these compounds, which lead to substituted stilbenes, occur with inversion at each asymmetric carbon atom. In the crystal, C—H...Br and C—H...O hydrogen bonds link the molecules into a tri-periodic intermolecular network.
