With the aim of rationalizing the experimental counterion- and solvent-dependent reactivity in the gold(i)-catalyzed Meyer-Schuster rearrangement of 1-phenyl-2-propyn-1-ol, a computational mechanistic study unraveled the unexpected formation of a gold-oxetene intermediate via commonly unfavorable 4-endo-dig cyclization triggered by the counterion in low polarity solvents.
为了使金（i）催化的 1-苯基-2-丙炔-1-醇 Meyer-Schuster 重排中实验性抗衡离子和溶剂依赖性反应性合理化，通过在低极性溶剂中由抗衡离子引发的通常不利的 4-endo-dig 环化反应，计算力学研究揭示了意想不到的金-氧杂环丁烷中间体的形成。
