Efficient Catalyst for Hydroarylation Reaction of Styrene with Phenol to Obtain High DSP Selectivity in Mild Condition

The Use of Dual Catalysts to Obtain High Selectivity for di‐Styrenated Phenol in the Reaction between Styrene and Phenol

“…Hydroarylation reactions of styrene with phenol using various single catalysts, such as inorganic acids, organic acids, Lewis acids, and metal salt catalysts, have been reported previously . The mixture of phenol and styrene was stirred for 6 h at 120°C with no solvent, using phenol/styrene/ catalyst mole ratio of 1/2/0.1, using various catalysts ( CH 3 CO 2 H, CF 3 CO 2 H, CH 3 SO 3 H, p ‐toluenesulfonic acid, HCl, H 2 SO 4 , AlCl 3 , AuCl 3 , BF 3 , CuBr, CuBr 2 , CuCl, CuCl 2 , FeCl 3 , Fe(OAc) 2 , FeSO 4 , InCl 3 , TiCl 4 , ZnCl 2 , Zn(OAC) 2 ).…”
