研究了在无溶剂条件下，以N-四丁基氟化铵(TBAF)为催化剂，以氢硅烷为还原剂，由环状碳酸盐合成甲醇和二醇。甲醇的有效收率为93%(从碳酸亚丙酯)，也可以从一系列其他碳酸盐中获得，这些碳酸盐都是从相应的环氧化物和二氧化碳中衍生出来的。同时，以优异的产率(例如，93%的丙二醇来自碳酸亚丙酯)形成了相应的二元醇。标记实验允许在常压下高产率地制备(CD3OD)-C-13或(CH3OH)-C-13。
The synthesis of methanol and diols from cyclic carbonates using N-tetrabutylammonium fluoride (TBAF) as a simple metal-free catalyst, and hydrosilanes as the reducing agent, under solvent-free conditions, is described. Methanol was efficiently obtained in 93% yield (from propylene carbonate) and also from a range of other carbonates that were all derived from their corresponding epoxides and CO2. Concomitantly, the corresponding diol was formed in excellent yields (e.g., 93% of propylene glycol from propylene carbonate). Labeling experiments allowed the preparation of (CD3OD)-C-13 or (CH3OH)-C-13 in high yield at atmospheric pressure.
