一系列Cp* IrX 2（NHC）型配合物的制备为甲醇-d（4）中各种有机分子的H/D交换提供了有效的催化剂。该反应在较温和的反应条件下进行，产率高于迄今为止报道的Cp*Ir体系。为了比较的目的，我们还研究了Cp* IrCl 2（PMe 3）在相同反应条件下的催化活性。两个新的Cp*Ir（NHC）配合物的分子结构进行了描述。
The preparation of a series of complexes of the type Cp*IrX2(NHC) provides effective catalysts for the H/D exchange of a wide range of organic molecules in methanol-d(4). The reaction proceeds with higher yields under milder reaction conditions than previous Cp*Ir systems reported thus far. For comparative purposes, we also studied the catalytic activity of Cp*IrCl2(PMe3) under the same reaction conditions. The molecular structures of two of the new Cp*Ir(NHC) complexes are described.
