The role of the OH group appears to be multifactoral, with facilitating oxidative addition and generation of the catalytic active Pd(0), enhancing the metathesis step between base and halide, preventing catalyst poisoning by solvation, decreasing its nucleophilicity.
在Suzuki反应中,高的溶剂化能可以从帮助催化剂活性中心产生、促进底物氧化加成、加速卤素亲核转移、抑制催化剂中毒四方面加速催化循环和提高产率。

负载型金属催化剂的传统制备方法为溶液浸渍法,浸渍法制备负载型金属催化剂的过程中,受到浸渍溶液表面张力及溶剂化效应的影响,金属活性组分前驱体以聚集形式沉积于载体表面,随后的干燥和焙烧过程使聚集程度进一步加剧,因此不能得到金属活性组分高度分散的催化剂。
