Abstract

The hydridomethyl(silyl)iridium(III) complex Ir{η2-Me2Si(CH2)2PPh 2}(PMe3)2 (2) reacted quantitatively with PMe3 at 60 °C to give the {(2-phosphinoethyl)silyl}tris(tertiary phosphine)iridium(I) complex Ir{η2-Me2Si(CH2)2PPh 2}(PMe3)3 (3) as reddish orange crystals through the reductive elimination of methane. X-ray crystal structure analysis revealed that 3 adopts a slightly distorted five-coordinate, trigonal-bipyramidal geometry with the silyl ligand occupying an axial site. Complex 3 generates the 16e silyliridium(I) complex Ir{η2-Me2Si(CH2)2PPh 2}(PMe3)2 (A) easily at room temperature.
