| dc.description.abstract | The successive reaction of chromium and tungsten hexacarbonyl, (CO)6M (M = Cr, W), with [NC(Ph)R]− and [Et3O]BF4 yields the alkylideneamino(ethoxy)carbene complexes (CO)5M[C(OEt)NC(Ph)R] (M = Cr (1), W (2); R = NMe2 (a), tBu (b)). Ethoxide abstraction from 1 and 2 affords 2-azoniaallenylidene complexes, {(CO)5M[CNC(Ph)R]}+BF4− (3/4). The complexes 3 and 4 are best described as resonance hybrids of several limiting structures. On the basis of the spectroscopic data of the complexes 3a and 4a the limiting structure of an iminium-substituted isocyanide complex dominates. | eng |

| kops.description.abstract | Die sukzessive Reaktion von Hexacarbonylchrom und -wolfram, (CO)6M (M = Cr, W), mit [NC(Ph)R]− und [Et3O]BF4 gibt Alkylidenamino (ethoxy)carben-Komplexe (CO)5M[C(OEt)NC(Ph)R] (M = Cr (1), W (2); R = NMe2 (a), tBu (b)). Durch Ethoxid-Abspaltung aus 1 und 2 erhält man 2-Azoniaallenyliden -Komplexe, (CO)5M[CNC(Ph)R]+BF4− (3/4). Die Komplexe 3 und 4 werden am besten als Resonanzhybride mehrerer Grenzstrukturen beschrieben, wobei aufgrund der spektroskopischen Daten bei 3a und 4a die Grenzform eines iminiumsubstituierten Isonitril-Komplexes dominiert. | deu |
