Palladium diacetate Use and Manufacturing

Methods of Manufacturing

Recycling palladium powder (10.3 g, 0.9 equiv) was added into AcOH (200 ml) and HNO3(0.5 ml), followed by refluxing for 30 min. When the reaction was stopped, the hot brownsolution was filtrated. The solution was concentrated until a little AcOH (~20 ml) was left.At room temperature, Pd(OAc)2 crystals precipitated at the bottom of beaker. Throughfiltration, we obtained recycling Pd(OAc)2 (20 g, 92percent).

Uses

A catalyst for intramolecular coupling.

Manufacturing Info：

Acetic acid, palladium salt (1:?): INACTIVE|Acetic acid, palladium(2+) salt (2:1): ACTIVE
