    Description / Table of Contents: Reaction of Cyanates with 3-PyrazolidinonesAddition of 3-pyrazolidinones 1 to cyanates 2 (phenyl, 2,2,2-trichloroethyl, and trifluoroethyl cyanate) leads to the N-1-carboximidates 3 which have been transformed into the hydrochlorides 6. The IR and 1H-NMR spectra of 3 and 6 are compared with those of the N-1-carbamoyl derivates 4 and of the N-1-benzoyl derivates 5.
    Notes: Addition von 3-Pyrazolidinonen 1 an Cyansäureester 2 (Phenyl-, 2,2,2-Trichlorethyl-, 2,2,2-Trifluorethylcyanat) ergibt die N-Imidsäureester 3, die in die Hydrochloride 6 übergeführt wurden. Die IR- und 1H-NMR-Spektren von 3 und 6 werden mit denen der N-1-Carbamoyl-Derivate 4 und der N-1-Benzoyl-Derivate 5 verglichen.
