bases, Pd-catalyzed transfer hydrogenations with formic acid were found to be facile processes. These new conditions produce innocuous carbon dioxide as the by-product compared to the use of ammonium formate, which generates ammonia and carbon dioxide as gaseous by-products which recombine to create unsafe conditions. When the substrate is basic enough to form salts with formic acid, no additional base
在催化量的有机碱的存在下,发现用甲酸进行钯催化的转移加氢是简便的方法。与使用甲酸铵相比,这些新条件会产生无害的二氧化碳副产物,而甲酸铵会生成氨和二氧化碳,而气态副产物会重新结合形成不安全的条件。当底物碱性足以与甲酸形成盐时,则无需额外的碱。在某些情况下,反应产物用于加速转移氢化过程。
