    • 2 proton signals could be observed as a multiplet [part of an AA′XX′ (5a,5b,8) or ABX system (11)] at δ=0.2-0.4. While the strong solvent signals (THF) at δ=1.85 and 3.75 obscured some parts of the spectrum, a distinct signal of the starting alkyl iodide could always be monitored to follow the progress of the reaction.
