应用

Pd/C 和 Pd(OH)2/C 的加成反应可提高 N- 或 O-脱苄基反应的效率。
在分子内和分子间过程中高效催化芳基碘和芳基溴的直接芳基化反应。
对苄基-氮键的氢解反应特别有效,并且已证明即使对于其他碳负载钯催化剂失效的情况也同样有效。

[reactions: see text] Palladium hydroxide on carbon (Pearlman's catalyst) effectively catalyzes direct arylation reactions of aryl iodides and bromides, providing excellent arylation-to-hydrodehalogenation ratios (>30:1) with broad scope for both intra- and intermolecular arylation processes. Studies aimed at determining the nature...
