We have prepared highly efficient radical probes 2a−b involving the hex-5-enyl rearrangement. The reaction of 2a−b with active magnesium leads to the cyclized products 4a−b, providing a direct evidence of radical intermediates during the formation of aryl Grignard reagents. The variations of yields for cyclized products 4a−b as a function of structural modifications in 2a−b suggest that the intervention of dianions is not necessary to explain the observed results. |
