  Reactivity of [Re(η2-H2)(CO)2P3]+ cations with alkynes: preparation of vinylidene and propadienylidene complexes

  摘要：

  Treatment of [Re(eta(2)-H-2(CO)(2)P-3](+) cations with phenylacetylene leads to the displacement of H-2 and the formation of vinylidene [Re{C=C(H)Ph}(CO)(2)P-3](+) (1-3) [P = P(OEt)(3), PPh(OEt)(2) or PPh2OEt] derivatives. Infrared and NMR data support equilibrium in solution [Re(CO)(2)P-3](+) + PhC=H reversible arrow [Re{=C=C(H)Ph}(CO)(2)P-3](+) involving the unsaturated complex, free alkyne and vinylidene derivative. 1,4-Diethynylbenzene also tautomerises to the Re(I) centre, affording the [Re{=C=C(PI)(1,4-C6H4C=CH)}(CO)(2)P-3]BF4 [P = P(OEt)(3) or PPh(OEt)(2)] vinylidene derivatives. Vinylidene complexes 1-3 are deprotonated easily by NEt3 to give acetylides Re(C=CR)(CO)(2)P-3 (4-6) (R=Ph or 1,4-C6H4C=CH), which may in turn be reprotonated with HBF4. Et2O to reform vinylidenes 1-3. Acetylide complexes 4-6 were also prepared by reacting unsaturated cations [Re(CO)(2)P-3](+) with lithium acetylide. Binuclear complexes {Re(CO)(2)P-3}(2)(mu-1,4-C=CC6H4C=C) (7, 8) [P = PPh(OEt)(2) or PPh2OEt] were obtained by sequential treatment of [Re(CO)(2)P-3](+) cations, first with 1,4-HC=CC6H4C=CH and then with an excess of NEt3. Propadienylidene complexes [Re(=C=C=CPh2)(CO)(2)P-3]BF4 (9, 10) [P=PPh(OEt)(2) or PPh2OEt] were prepared by allowing[Re(eta(2)-H-2)(CO)(2)P-3](+) cations or unsaturated species [Re(CO)(2)P-3](+) to react with HC=CC(Ph-2)OH at room temperature. The characterisation of all new complexes by IR and H-1-, P-31{H-1}- and C-13{H-1}-NMR spectra is also discussed. (C) 2000 Elsevier Science S.A. All rights reserved.

  cyanoguanidine. Bis(diethylcyanamide) complexes MBr(NCNEt2)2(CO)3 (6, 7) were prepared by allowing pentacarbonyl species MBr(CO)5 to react with an excess of cyanamide NCNEt2. The complexes were characterised by spectroscopy (IR, 1H, 31P, 13C NMR) and by X-ray crystal structure determination of [Mn(NCNEt2)(CO)2PPh(OEt)2}3]BPh4 (2a) and ReBr(NCNEt2)2(CO)3 (7a).
