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.

一种新的不含膦的嘧啶基甲ligand基配体及其钯（II）络合物是由易于凝视的原料合成的，并且已经研究了其作为交叉偶联催化剂即铃木-宫浦（SMC）的能力。首先，在苯基硼酸和对溴苯乙酮的交叉偶联中研究了该预催化剂，由于其反应性和作为可用于模型交叉偶联反应的低成本溴化物而选择了对溴苯乙酮。新的钯（II）配合物在常规和微波辐照条件下作为芳基卤化物与硼酸的各种衍生物在水中SMC的SMC的前催化剂显示出很高的适用性，并且在温和的反应条件下以优异的收率获得了交联产物。
