Extracurricular laboratory: Synthetic route of Tris(dibenzylideneacetone)dipalladium-chloroform

The chemical industry reduces the impact on the environment during synthesis, Tris(dibenzylideneacetone)dipalladium-chloroform, , I believe this compound will play a more active role in future production and life.

Tris(dibenzylideneacetone)dipalladium-chloroform, A common heterocyclic compound, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.”52522-40-4

General procedure: To 64.3 mg (0.278 mmol) of TTbQ-Me dissolved in anhydrous acetone (20 ml) in a two necked flask, 30 mg (0.278 mmol) of p-benzoquinone and 120 mg (0.116 mmol) of Pd2DBA3CHCl3 were added in sequence under inert atmosphere (Ar). The resulting mixture was stirred in the dark for 30 min, filtered on a celite filter and evaporated under vacuum to a small volume. Addition of Et2O induces the precipitation of the complex which was filtered off and dried in a desiccator for 5 h. 82.2 mg of the title compound as a red solid were obtained (yield 80percent).
