Reindl, David 2013-06-27T16:18:42Z Fischer, Helmut Roth, Gerhard deposit-license Fischer, Helmut Troll, Carsten Troll, Carsten Reindl, David 1993 Diarylallenylidene(pentacarbonyl)-chromium and -tungsten complexes, (CO)5M=C=C=CR<sub>2</sub> (M = W (1), Cr (2)), react with amines, imines and hydrazines by addition of the nitrogen nucleophile to the C<sub>α</sub>allenylidene atom. With NEt<sub>3</sub> the adduct formation is reversible. With secondary and primary amines, imines and hydrazines, the initially formed N-ylide complexes react readily further to give carbene, azetidinylidene and nitrile complexes, respectively. For example the reaction of (a) 1 and 2 with HNEt<sub>2</sub> or H2NPh gives alkenyl(amino)carbene complexes, (CO)<sub>5</sub>M=C [C(H)=CR<sub>2</sub>] NR′<sub>2</sub> (3–5); (b) of 1 and 2 with HN=CR<sub>2</sub> gives alkenyl(alkylideneamino)carbene complexes, (CO)<sub>5</sub>M=C [C(H)=CR<sub>2</sub>] [N=CR′<sub>2</sub>] (6,7); (c) of 1 with (iPr)N=C(Ph) H the azetidinylidene complex 9; (d) of 1 with 1,2-disubstituted hydrazines such as H(Me)NN(R)H (R = Me, Ph) alkenyl (hydrazino)carbene complexes, (CO)<sub>5</sub>M=C [C(H)=CR<sub>2</sub>] [N(Me)N(R)H] (11) and (e) of 1 with H<sub>2</sub>NNR<sup>1</sup>R <sup>2</sup> (R<sup>1</sup> = R<sup>2</sup> = H, Me; R<sup>1</sup> = H, R<sup>2</sup> = Ph) alkenyl(amino)carbene complexes (13) and/or aciylnitrile complexes, (CO)<sub>5</sub>W[N = C-C(H=CR<sub>2</sub>] (12). The structures of representative examples of 6, 11 and 12 were established by X-ray analyses.
