A mild and efficientsynthesis of N-acylhydrazones has been developed, applying a simple grindstone procedure, leading to a library of 51 examples exhibiting a broad variety of structural features, 21 of them described for the first time in this paper. This methodology works without any organic solvent under the catalysis of acetic acid at room temperature, promotes the formation of essentially pure

undergo either alkylation or conversion to thiolcarboxylate esters when treated with substituted chlorothiolformates in the presence of aluminiumchloride. While aryl or primary alkyl chlorothiolformates provide the corresponding thiol-esters, text-butyl chlorothiolformate gives only alkylation products derived from the tert-butyl cation. Competitive alkylation and acylationreactions occur when isopropyl

de ferrocenoylhydrazone (H2L) and the octahedral nickel(II) complex [Ni(HL)2] · 2CH3OH (I) are synthesized and structurally characterized (CIF files CCDC 981876 (H2L) and 981877 (I)). The crystalstructures of both compounds include two independent molecules with different mutual orientations of the tosyl and ferrocene fragments. In a single crystal of H2L, the independent molecules are joined by intermolecular

A protocol to access ferrocenecarboxylic acid via carboxylation of ferrocene with carbon dioxide in the presence of aluminum chloride was elaborated. An efficient microwave-assisted synthesis of ferrocenoyl hydrazones by condensation of ferrocene carbohydrazide with carbonyl compounds was developed. Structures of the synthesized compounds were examined by NMR spectroscopy and mass spectrometry. Structures
