A Close‐to‐Aromatize Approach for the Late‐Stage Functionalization through Ring Closing Metathesis

An efficient approach for the synthesis of monosubstituted aromatic compounds relying on a ring-closing metathesis followed by spontaneous 1,2-elimination is presented. The efficiency late-stage functionalization highlighted in various solvents (up to 920 TON). This compatible with strained cycles and other multiple bonds substrate.
