Catalytic Hydrodechlorination of Trichlorobenzenes with Pd(Phen)‎Cl2 as Catalyst Precursor

الملخص EN

We reported the catalytic hydrodechlorination (HDC) of trichlorobenzenes by an organometallic compound Pd(Phen)Cl2 as a catalyst precursor.

The catalyst precursor was prepared by chemical coordination reaction and characterized by FTIR and 1H NMR techniques.

The HDC performance of Pd(Phen)Cl2 as catalyst precursor was evaluated on 1,2,3-, 1,2,4-, and 1,3,5-trichlorobenzenes (TCBs).

All TCBs could be converted to dechlorination products with high conversion.

Products distribution was closely related with the substrate structures and C-Cl bond energies.

A reasonable reaction mechanism was also proposed.
