    • Interestingly, the magnesium derivative of methyl 4-pivaloxy-3- iodobenzoate is also unstable and rapidly decomposes at -78°C.

    • note
    • Besides 7 (48% yield), we also isolated an iodoketone (2-[3-(2-furyl)propanoyl]-4-iodophenyl 4-chlorobenzenesulfonate), which probably formed through protonation of the corresponding Grignard reagent.
