- W1986275632 abstract "Aminocarben-Komplexe LnM = C(NH2)R 1 [LnM = Cr(CO)5, R = C6H5, CH3] lassen sich durch Kondensation ihrer NH2-Gruppe mit Carbonylverbindungen O=CYR1 in 2-Azaallenyl-Komplexe LnM⊖ [C(R)=N⊕=CXR1] umwandeln. Die Kondensation gelingt mit Et3N bzw. POCl3/Et3N und einer überraschenden Vielfalt sonst recht unterschiedlich reagierender Carbonylverbindungen, wie Aldehyde (Y = H), Säurechloride (Y = Cl), Säureamide [Y = N(CH3)2]. Es wurden 2-Azaallenyl-Komplexe mit bisher nicht zugänglichen Substitutionsmustern [X = H (3), O2CR1 (7), N(CH3)2 (9)] erhalten und spektroskopisch analysiert. 3a wurde anhand einer Kristallstrukturanalyse charakterisiert. Organic Synthesis via Transition Metal Complexes, 33. – 2-Azaallenyl Chromium Complexes by Condensation of Aminocarbene Chromium Complexes with Aldehydes, Acid Chlorides, or Acid Amides Aminocarbene complexes LnM = C(NH2)R 1 [LnM = Cr(CO)5, R = C6H5, CH3] can be converted to 2-azaallenyl complexes LnM⊖ [C(R)=N⊕=CXR1] by the condensation of the NH2 group with organic carbonyl compounds O=CYR1 in presence of Et3N and POCl3/Et3N, respectively. The condensation is achieved with a surprisingly wide variety of different carbonyl compounds like aldehydes (Y = H), acid chlorides (Y = Cl), acid amides [Y = N(CH3)2] and leads to the formation of 2-azaallenyl complexes of hitherto unknown substitution patterns [X = H (3), O2CR1 (7), N(CH3)2 (9)]. These have been analysed spectroscopically. 3a was characterized by an X-ray analysis." @default.
