Abstract

Abstract o-Benzenediazonium carboxylates couple with methylene-active compounds to yield hydrazo derivatives with high purity. The 1 H and 13 C NMR data of eleven such products are presented and analysed. The predominance of the hydrazo over the azo form is consistent with accepted criteria. Furthermore, evidence for the preference of the carbethoxy group over the acetyl group for intramolecular hydrogen bonding is suggested.
