Abstract

The first iridium (I) complex containing siloxyl and N-heterocyclic carbene ligand such as [Ir (cod)(IMes)(OSiMe3)](1) and [Ir (CO) 2 (IMes)(OSiMe3)](3) have been synthesized and their structures solved by spectroscopy and X-ray methods as well as catalytic properties in selected hydrogenation reactions have been presented in comparison to their chloride analogues, ie [Ir (Cl)(cod)(IMes)](2) and [Ir (Cl)(CO) 2 (IMes)](4). The attempts at synthesis ...
