Oxidative addition of SiH4 and GeH4 to Ir(PPh3)2(CO)Cl: structural and spectroscopic evidence for the formation of products derived from cis oxidative addition

Author affiliations

Abstract

X-ray diffraction studies demonstrate that oxidative addition of SiH4 to Ir(PPh3)2(CO)Cl yields Ir(PPh3)2(CO)(Cl)(SiH3)H, which features a cis arrangement of the SiH3 and H ligands in which H is located trans to CO, rather than trans to Cl as originally reported. 1H NMR spectroscopic studies indicate that oxidative addition of GeH4 to Ir(PPh3)2(CO)Cl also occurs in a cis manner but results in the formation of two isomers of Ir(PPh3)2(CO)(Cl)(GeH3)H, which are related by H being trans to either CO or Cl.
