摘要：
Organic Syntheses via Transition Metal Complexes, 47. — 1‐Chroma‐1,3‐dienes by Aminoalkenylation of Methylcarbene Chromium Complexes with Secondary Amides 4‐(NH‐Amino)‐1‐chroma‐1,3‐dienes [= β‐(NH‐Amino)alkenylcarbene chromium complexes] (CO)5CrC(OEt)CHC‐(NHMe)R (Z)‐6 (R  Me, Et, iPr, tBu, Ph) have been obtained with high stereoselectivity in 53–69% yields by the aminoalkenylation of (CO)5CrC(OEt)Me (1a) with secondary amides OC(NHMe)R (5, R  Me, Et, iPr, tBu, Ph) in the presence of POCl3/Et3N.
