Abstract
The reaction of the vinylidene complexes [(C5H5)(CO)(NO)W=C=C(H)RI (10a: R = tBu; 10b: R = Ph) with the arsaalkene tBuC(O)-As=C(NMe2)(2) (11) afforded the novel eta(2)-1-arsaallene complexes [eta(2)-{tBuC(O)-As=C=C(H)R}W(CO)(NO)-C5H5] (13: R = tBu; 15: R = Ph). Similarly, treatment of 10a with the ferrioarsaalkene [(C5Me5)(CO)(2)Fe-As=C(NMe2)(2)] (12) led to the formation of [eta(2)-{[(C5Me5)(CO)(2)Fe]-As=C=C(H)tBu}W(CO)(NO)(C5H5)] (14), whereas combination of 12 and 1 Ob yielded the carbene complex [(C5H5) (CO) (NO)W=C(NMe2)C(Ph)=C(H)NMe2] (16) in high yield instead of the anticipated arsaallene complex. The novel compounds 13, 14, 15 and 16 were characterised by elemental analyses and by means of spectroscopy (IR, H-1, C-13 NMR). Moreover, the molecular structures of 14 and 15 were elucidated by X-ray diffraction analyses. (c) Wiley-VCH Verlag GmbH & Co. KGaA.
