| 中文摘要: |
| 报道了硫酸钴－乙酸在室温、无溶剂条件下催化醇和酚的四氢吡喃化反应。硫酸钴－乙酸作为协同催化体系，二者缺一不可。与传统催化剂相比，新催化体系的催化活性最好。反应结束后，硫酸钴经简单相分离可回收，重复使用多次催化活性无明显下降。提出了可能的催化反应机理。 |
| 英文摘要: |
| Cobalt sulfate-acetic acid is found to catalyze the tetrahydropyranylation of alcohols and phenols efficiently at room temperature under solvent-free conditions. It is a synergistic catalytic system, and both cobalt sulphate and acetic acid are indispensable for the rate acceleration of the reaction. Compared with other conventional catalysts, cobalt sulphate-acetic acid proved to be the best. After reaction, cobalt sulphate can be easily recovered by simple phase-separation and reused for many times without deterioration in catalytic activity. A probable reaction mechanism is proposed. |
