General description

tBuBrettPhos Pd G3 是第三代 (G3) Buchwald 预催化剂，可用于交叉偶联反应，形成 C-C、C-N、C-O、C-F、C-CF3 和 C-S 键。它具有空气、水分和热稳定性，可溶于多种常见有机溶剂。它具有催化剂用量少、反应时间短、能有效地形成活性物种和精确控制配体钯比等特点。

Application

tBuBrettPhos Pd G3 已被用作在温和反应条件下氨基酸酯与芳基三氟甲磺酸酯的 N -芳基化的预催化剂，且氨基酸酯的消旋作用极小。它也可用于在苯甲醛肟作为氢氧化物替代物存在下催化芳基卤化物转化为酚类。

对于小规模和高通量应用，产品为 ChemBeads (928313)
