Aminocarbene complexes LnM=C(NH2)R 1 can be converted to 2-azaallenyl complexes LnM-+=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 and leads to the formation of 2-azaallenyl complexes of hitherto unknown substitution patterns 1 (7), N(CH3)2 (9)>.These have been analysed spectroscopically. 3a was characterized by an X-ray analysis. - Keywords: 2-Azaallenyl chromium complexes/ CNC building blocks/ Aminocarbene complexes
