 Title    Reaktionen von Komplexliganden, LVI [1]. 3-Pyrrolylcarben-Komplexe des Chroms: Darstellung und neuartige Carbenanellierung zum Isoindol-Gerüst Reactions o f Complex Ligands, LVI [1], 3-Pyrrolylcarbene Complexes of Chrom ium: Synthesis and Carbene Annulation to the Isoindole Skeleton  
 Abstract    -bromo-2,5-dimethylpyrrols, accessible from low-temperature brom ination using NBS or BTMABT, have been modified into pentacarbonyl[methoxy(3-pyrrolyl-car-bene)] complexes via sequential halogen/lithium exchange, addition to hexacarbonyl chro­ mium and alkylation. These com pounds react with alkynes and amines, resp., to give amino-lysis and annulation products. The carbene annulation methodology has been exploited in the synthesis of a persubstituted isoindoloquinone.
