Abstract
:
In this study, the use of Pd(II) loaded NaY type zeolite as a catalyst in the Suzukiinvestigated.For this aim, Pd(OAc)2, and [Pd(NH3)4]Cl2 complexes were loaded into NaY zeolite in order to form an appropriate catalyst system. Pd(NH3)42+ loaded Y type zeolite was calcined to obtain Pd(II) form Pd(OAc)2 loaded Y type zeolite showed high activity in the reactions of 4-iodoanisole and 4-bromoanisole with arylboronic acid. However the reusability which is an important property of heterogeneous catalyst could not be provided, the following studies were continued with Pd(II) loaded Y type zeolite.When, 4-iodo and 4-bromoanisole reactives were used in the presence of Pd(II) loaded Y type zeolite, 60-100% biaryl products were obtained. The amount and type of the base and DMF:H2O ratio have high effects on the yield. In order to prove that the reaction took place in heterogeneous phase, at the end of the reaction Pd analysis of the solution was performed by AAS technique. It was found that the Pd amount in solution was trace.
