[C6H4CH2NMe2}-2]− (CN) was prepared via a multiple CH activation reaction. Ligand exchange in the parent model species [PtCl(C6H3CH2NMe2}-2-SiMe3-5)(DMSO)] (1) in the presence of PPh3 gave the phosphine complex [PtCl(C6H3CH2NMe2}-2-SiMe3-5)(PPh3)] (2). The crystal structure of 2 was also determined, showing a close proximity between one of the ArH of the phosphine ligand and the ArHortho of the
通过多次CH活化反应,制备了一系列附有单阴离子C,N双齿
