摘要
在紫外光照射下烯烃的氢甲酯化反应能在常温常压条件下完成 ,系统地研究了不同钴盐催化剂的反应规律及酸碱性对反应的影响。发现醋酸钠可大大提高反应的选择性及产率 ,提出了醋酸钠作用的初步机理 ,即对反应体系酸碱性的调节及醋酸钠与催化剂的相互作用。
Under irradiation of UV light the methoxycarbonylation of olefins was performed at ambient conditions and the different cobalt salt catalysts and the effects of acid and base on the reaction were systematically studied. It has been established that the selectivities and yields can be greatly increased by the addition of sodium acetate. A preliminary mechanism of the role sodium acetate plays was proposed: regulating pH of the reaction solution and interacting with catalysts.
