摘要

一个简洁的K2CO3/ tfaa介导的易于获得的磺酰邻羟基苯乙酮与邻硝基二硫化物的二芳化描述。这种单步策略通过形成一碳-碳单键和一碳-氧单键，提供了多种功能化磺酰基C-和o-双-o-硝基苯乙酮。提出并讨论了一种合理的机理。通过x射线分析确定了关键产物的分子结构。

K2CO3/TFAA-activated diarylation of α-sulfonyl o-hydroxyacetophenones with o-nitroaryl disulfides to construct sulfonyl bis-o-nitroaryl acetophenones†

A concise K₂CO₃/TFAA-mediated diarylation of readily accessible sulfonyl o-hydroxyacetophenones with o-nitroaryl disulfides is described. This single-step strategy provides a variety of functionalized sulfonyl C- and O-bis-o-nitroaryl acetophenones via the formation of one carbon–carbon single bond and one carbon–oxygen single bond. A plausible mechanism is proposed and discussed. The molecular structures of key products were determined by X-ray analysis.
