The direct α-alkylation of ketones with alcohols has emerged as a new green protocol to construct C-C bonds with H2 O as the sole byproduct. In this work, a very simple and convenient Pd/C catalytic system for the direct α-alkylation of ketones with primary alcohols in pure water is developed. Based on this catalytic system, aqueous mixtures of dilute acetone, 1-butanol, and ethanol (mimicking ABE fermentation products) can be directly transformed into C5 -C11 or longer-chain ketones and alcohols, which are precursors to fuels.
酮与醇的直接 α-烷基化反应作为一种新型的绿色合成方法,以 H2O 为唯一副产物,构建 C-C 键。在这项工作中,开发了一种非常简单方便的 Pd/C 催化体系,用于在纯水中实现酮与伯醇的直接 α-烷基化反应。基于该催化体系,稀丙酮、1-丁醇和乙醇的水相混合物(模拟 ABE 发酵产物)可以直接转化为 C5-C11 或更长链的酮和醇,这些物质是燃料的前体。
