摘要

对标题中的双对映砜进行的结构分析表明，它是赤式（RR/SS）异构体，并且在证明这些化合物的 1,3-消除反应（导致取代的二苯乙烯）在每个不对称碳原子上发生反转的过程中发挥了关键作用。标题化合物 C16H17BrO2S 结晶为一对砜的赤式（RR/SS）异构体，由于砜硫原子上 α 碳原子的手性，这对砜是非对映异构体。结构分析表明，这些化合物的 1,3 消去反应在每个不对称碳原子上发生反转，从而生成取代的二苯乙烯。在晶体中，C-H⋯Br 和 C-H⋯O 氢键将分子连接成一个三周期分子间网络。下载：下载高清图片 (302KB)Download ：下载全尺寸图片

erythro-{1-Bromo-1-[(1-phenylethyl)sulfonyl]ethyl}benzene

Structural analysis of the title diasteromeric sulfone determines this to be the erythro (RR/SS) isomer, and 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.

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.
