Anodic oxidation of unsaturated α-stannyl ethers in Bu4NClO4âCH2Br2 results in effective cyclization and the introduction of bromide into one of the original olefinic carbons; a mechanism involving the coupling between the cyclized carbocation and Brâ generated by cathodic reduction of CH2Br2 is suggested.
