Abstract
A new phosphine-free pyrimidylformamidine-based ligand and its palladium(II) complex has been synthesized from easily accesible staring materials and its ability to be a catalyst for cross-coupling reactions namely Suzuki–Miyaura (SMC) has been investigated. Firstly, the precatalyst was examined in cross-coupling of phenylboronic acid and p-bromoacetophenone which is selected due to its reactivity and as a low cost bromide that could be used for model cross-coupling reaction. The new palladium(II) complex showed high applicability as a precatalyst for SMC of aryl halides with various derivatives of boronic acid in water under conventional and microwaves irradiation conditions and the cross coupled products were obtained in excellent yields under mild reaction conditions.
