Front Cover: Hydroiodination‐Triggered Cascade Reaction with I₂/PPh₃/H₂O: Metal‐Free Access to 3‐Substituted Phthalides from 2‐Alkynylbenzoates (Eur. J. Org. Chem. 36/2017)

Abstract

The Front Cover shows a cascade reaction under metal‐free conditions. The reaction depicts a waterfall (cascade) and a place that is not usually associated with a metal (forest). Easily available reagents, i.e., triphenylphosphine, iodine, and water, trigger the cascade reaction, which includes desilylation, hydroiodination, cyclization, and reduction to give phthalides from 2‐(trimethylsilylalkynyl)benzoates. We acknowledge Tamami Yamaguchi for taking the picture of a waterfall at Plitvice Lakes National Park. More information can be found in the https://doi.org/10.1002/ejoc.201700839
