ionic carbene complexes [Ir(RCNHMe)Cl(CO)(PPh3)2-(O3SCF3)]O3SCF3]O3SCF3 (R Ph or PhCH2) have been isolated from the reactions of trans-[IrCl(CO)(PPh3)2] with the nitrilium triflate salts, [RCNMe]O3SCF3. The major products from these, and the similar reactions of the nitrilium salts where R Me or But, are amorphous, yellow complexes [Ir(RCNHMe)Cl(CO)(PPh3)2O3SCF3.
离子卡宾配合物[Ir(RCNHMe)Cl(CO)(PPh 3)2-(O 3 SCF 3)] O 3 SCF 3 ] O 3 SCF 3(RPh或PhCH 2)的收率低从反式-[IrCl(CO)(PPh 3)2 ]与
三氟甲磺酸腈盐[RCNMe] O 3 SCF 3的反应中分离得到。这些化合物的主要产物以及RMe或Bu t的腈盐的类似反应是无定形的黄色络合物[Ir(RCNHMe)Cl(CO)(PPh 3)2 O 3SCF 3。
