3-Iodothioanisole is a meta-substituted aromatic thio-ether that couples an electron-donating methylthio group with an aryl iodide handle. The C–I bond is highly labile toward:
Oxidative addition with Pd, Ni or Cu catalysts, enabling mild Suzuki, Heck, Sonogashira and Buchwald–Hartwig cross-couplings to deliver meta-substituted bi-aryl sulfides, sulfoxides or sulfones (dioxane, 50–100 °C) ;
Halogen–lithium exchange (n-BuLi, –78 °C) giving 3-lithio-thioanisole, which is quenched with electrophiles (B(OR)₃, CO₂, R-CHO) to furnish boronic acids, carboxylic acids or benzylic alcohol scaffolds;
Chemoselective S-oxidation (H₂O₂/AcOH, rt, 1 h) to the corresponding sulfoxide or sulfone, providing late-stage diversification for agro-chemical, dye and fragrance applications.
The product shows excellent shelf-life (≥ 24 months when stored sealed, dry and under nitrogen) and is supplied with batch-specific COA, GC-MS, NMR and MSDS documentation suitable for cGMP or ISO-9001 workflows.
