| The reduction of acetophenone 1a, propiophenone 1b, butyrophenone 1c, and isobutyrophenone 1d under similar conditions shown in Table 2 afforded the corresponding alkylbenzenes 2a¨Cd in excellent yields. The formation of a small amount of alcohols 3 in these reactions suggests that they are the de facto intermediates en route to the formation of 2. When 3a was treated with Ni¨CAl alloy in water under similar conditions to those described above, expected 2a was obtained in good yield. |
