Iridium-catalyzed redistribution of hydrodisilanes via a silyl(silylene)iridium(III) complex: Synthesis of a donor-stabilized silyl(silylene)iridium(III) complex

Article abstract of DOI:10.1246/cl.1997.437

Thermolysis of HMePhSiSiMe₃ in the presence of a catalytic amount of Ir{η²-Me₂Si(CH₂)₂PPh ₂}(PMe₃)₃ resulted in the redistribution of substituents to give its isomer HMe₂SiSiMe₂Ph. We propose the mechanism involving the 1,3-Me-shift on a silyl(silylene) complex, which was trapped as a donor-stabilized silyl(silylene)iridium(III) complex.
