Palladium colloids obtained from the degradation of Hermann–Beller palladacycle proved to be an efficient catalytic system in combination with silver oxide as a selective oxidant for the oxidative esterification of differently substituted benzyl alcohols in MeOH as solvent. Excellent reactivity exhibited by the catalytic system also allowed the alcoholic coupling partner to be changed from MeOH to
从Hermann-Beller palladacycle的降解中获得的钯胶体被证明是一种有效的催化体系,与氧化银作为选择性氧化剂结合使用,可在甲醇为溶剂的情况下对不同取代的苄醇进行氧化酯化。催化体系表现出的优异的反应性也使醇类偶合体从MeOH转变为具有各种功能的多种醇类。所开发方案的温和性还使得可以使用炔丙醇作为偶联伴侣,而没有观察到末端炔烃的任何干扰。使用开发的催化剂体系,在乙二醇和甘油的情况下,伯醇官能团相对于仲醇的选择性氧化偶联也是可能的。
