Synthesis and reactivity of propionyliridium complexes. Competitive reductive elimination of C-H and H-H bonds from a propionyldihydridoiridium complex
- Univ. of Rochester, NY (USA)
The complex Ir({eta}{sup 2}-C{sub 2}H{sub 4})(Et)(CO)(dppe) reacts with CO to produce initially Ir(Et)(CO){sub 2}(dppe), which then undergoes subsequent CO insertion and carbonylation to form Ir(C(O)Et)(CO){sub 2}(dppe). This latter complex was isolated and structurally characterized: space group P{bar 1} (no. 2), a = 11.046 (2) {angstrom}, b = 16.596 (4) {angstrom}, c = 8.523 (2) {angstrom}, {alpha} = 93.93 (2){degree}, {beta} = 110.94 (2){degree}, {gamma} = 95.24 (2){degree}, V = 1444 (1) {angstrom}{sup 3}, Z = 2. The complex Ir(C(O)Et)(CO){sub 2}(dppe) possesses a distorted trigonal-biyramidal geometry with the propionyl group in an axial position, the dppe ligand spanning the other axial and an equatorial position, and two equatorially disposed carbonyl groups.
