一般描述

It is an encapsulated catalyst (EnCat^®), wherein palladium acetate and triphenylphosphine (TPP) are microencapsulated within a polyurea matrix, which prevents palladium leaching.

应用

可回收利用的负载化催化剂体系，在 C-C 键的形成和还原过程中可简化钯的除去。

Reaxa Technology

Pd EnCat^® TPP30 may be used as a catalyst for the microwave-assisted Sonogashira cross-coupling of:

Aryl iodides and bromides with terminal alkynes to form the corresponding coupling products under copper-free conditions.
Bromobenzotriazoles and arylacetylenes in the presence of 1,5-diazabicyclo[5.4.0]undecene-5-ene (DBU) and copper iodide to form 2H-benzo[d][1,2,3]triazole derivatives.

特点和优势

The advantages of using Pd EnCat^® catalysts are:

low residual metal levels in crude product
easy recovery of catalyst
compatibility of immobilized metal with various ligands to effect C-C bond forming reactions
safer and easier to handle than Pd/C for hydrogenation
efficiency and economy gains through recovery and recycling
