Flash Communication:Cyanophosphide Transfer Reactions
Cyanophosphides of the general form [RPCN]<sup>−</sup> can be viewed as cyanide adducts of phosphinidenes and are phosphorus species in the (+1)-oxidation state. We have recently reported on the stable cyanophosphide [<sup>Dipp</sup>TerPCN]K (<sup>Dipp</sup>Ter = 2,6-Dipp<sub>2</sub>C<sub>6</sub>H<sub>3</sub>, Dipp = 2,6-<i>i</i>PrC<sub>6</sub>H<sub>3</sub>) and now investigate its reactions with ECl<sub><i>n</i></sub> (E = Ge, <i>n</i> = 2; E = P, As, <i>n</i> = 3) in either salt metathesis or base-assisted dehydrohalogenation reactions. In the case of GeCl<sub>2</sub>, salt metathesis with [<sup>Dipp</sup>TerPCN]K afforded the dimer of a chlorogermylene [<sup>Dipp</sup>TerP(CN)GeCl]<sub>2</sub>. When only 0.5 equiv of GeCl<sub>2</sub> was used, the diphosphanylgermylene [<sup>Dipp</sup>TerP(CN)]<sub>2</sub>Ge was generated in solution. With ECl<sub>3</sub> (E = P, As), facile cyanophosphide transfer was achieved from <sup>Dipp</sup>TerP(H)CN in NEt<sub>3</sub>-assisted dehydrohalogenation, giving diphosphanes or arsaphosphanes of the type <sup>Dipp</sup>TerP(CN)ECl<sub>2</sub> (E = P, As), respectively.
