cationic bis(3,5-dimethylpyrazol-1-yl)methane}-palladium(II) complexes of general formula [PdClXRCH(3,5-Me 2 pz) 2 }] (X=ClorMe) or [PdMe(MeCN)RCH(3,5-Me 2 pz) 2 }]-[BAr f 4 ], where R is a benzyl or benzyloxycarbonyl group or a poly(aryl ether) Frechet-type dendron, have been synthesized and fully characterized, including by X-ray diffraction methods in some cases. These palladium complexes have been
中性和阳离子双(3,5-二甲基吡唑-1-基)甲烷}-钯(II)配合物,通式为[PdClXRCH(3,5-Me 2 pz) 2 }] (X=ClorMe)或[ PdMe(MeCN)RCH(3,5-Me 2 pz) 2 }]-[BAr f 4 ],其中R是苄基或苄氧羰基或聚(芳醚)Frechet型树枝状化合物表征,包括在某些情况下通过 X 射线衍射方法。这些钯配合物已被评估为对碘甲苯和丙烯酸甲酯之间的 Heck 反应中的催化剂前体。由这些前体形成的活性催化物质显然没有与双(吡唑基)甲烷配体配位。
