Flash Communication: (Ph <sub>3</sub> P) <sub>2</sub> N <sub>2</sub> ─Aza-Wittig Reagent for Metal Carbonyls
Cr-(CO)<sub>6</sub>, Mo-(CO)<sub>6</sub>, W-(CO)<sub>6</sub>, and Fe-(CO)<sub>5</sub> undergo an aza-Wittig reaction with triphenylphosphinazine [(Ph<sub>3</sub>P)<sub>2</sub>N<sub>2</sub>]. These reactions address exclusively one CO ligand, yielding (isocyanoimino)-triphenylphosphorane metal complexes [(CO) <sub><i>x</i></sub> MCN<sub>2</sub>(PPh<sub>3</sub>)] (<b>1</b>: M = Cr, <i>x</i> = 5; <b>2</b>: M = Mo, <i>x</i> = 5; <b>3</b>: M = W, <i>x</i> = 5, <b>4</b>: M = Fe, <i>x</i> = 4). We present selective CO ligand deoxygenation at a metal center by an aza-Wittig reagent in the broad context of metallaheterocumulene fragmentation for carbon atom transfer.
