Synthesis of Aryl Trimethylstannane via BF<sub>3</sub>·OEt<sub>2</sub>‑Mediated Cross-Coupling of Hexaalkyl Distannane Reagent with Aryl Triazene at Room Temperature

BF<sub>3</sub>·OEt<sub>2</sub>-mediated cross-coupling of (SnMe<sub>3</sub>)<sub>2</sub> with aryl triazene offers a new strategy for the synthesis of aryl stannane. A variety of synthetically useful aryl trimethylstannanes were produced in moderate to good yields with this metal-free approach. One-pot sequential Stille cross-coupling with different aryl bromides provides a short entry to both symmetrical and unsymmetrical biaryl compounds.
