Abstract
The hydridomethyl(silyl)iridium(III) complex Ir(H)(Me){eta-Me(2)Si(CH2 )(2)PPh(2)}(PMe(3))(2) (2) reacted quantitatively with PMe(3) at 60 de grees C to give the {(2-phosphinoethyl)silyl}tris(tertiary phosphine)i ridium(I) complex Ir{eta(2)-Me(2)Si(CH2)(2)PPh(2)}(PMe(3))(3) (3) as r eddish orange crystals through the,reductive elimination of methane. X -ray crystal structure analysis revealed that 3 adopts a slightly dist orted five-coordinate, trigonal-bipyramidal geometry with the silyl li gand occupying an axial site. Complex 3 generates the 16e silyliridium (I) complex Ir{eta(2)-Me(2)Si(CH2)(2)PPh(2)}(PMe(3))(2) (A) easily at room temperature.
