| The reduction of acetophenone 1a, propiophenone 1b, butyrophenone 1c, and isobutyrophenone 1d under similar conditions shown in Table 2 afforded the corresponding alkylbenzenes 2a–d 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–Al alloy in water under similar conditions to those described above, expected 2a was obtained in good yield. |

在表2所示的條件下,減少苯乙酮(1a),苯丙酮(1b),苯丁酮(1c)和異丁酰苯(1d)的量,反應(yīng)產(chǎn)生的相應(yīng)烷基苯(2a)的量更高。反應(yīng)中有少量乙醇(3)產(chǎn)生,說明實(shí)際上乙醇是2形成過程中的中間產(chǎn)物。在如上所述的條件下,將3a與鎳鋁合金混合置于水中,則可以得到相當(dāng)產(chǎn)量的2a。 供LZ參考。 |
