偶联反应的幕后搭档——钯催化剂与它的搭档们
2026-08-04 · 推荐产品 · 百灵威授权转载
钯催化剂是现代有机合成中构建碳-碳键最有力的工具。从Heck反应、Suzuki-Miyaura偶联到Buchwald-Hartwig胺化，钯催化体系几乎支撑起了当代药物合成与精细化工的半壁江山。
钯催化剂的核心优势在于其温和的反应条件和卓越的官能团耐受性。零价钯是催化循环中的活性物种，能高效完成对芳基卤化物的氧化加成；二价钯前体则通过与膦配体或NHC配体的原位络合，灵活适配各类偶联反应的需求。近年来，NHC-钯催化剂因其突出的热稳定性和产率表现，在高温串联反应和C-H活化等挑战性场景中受到越来越多的关注。
百灵威提供涵盖多种钯源、配体、碱、溶剂与耗材的全品类产品，助力钯催化研究。
