Popis:	1. The reaction of 1-fluoroacyl-1,2-dimethylhydrazides with phenol and trifluoroacetic acid in a medium of CCl4 and MeCN takes place with the formation of a molecular H complex, and the oxygen atom in the C=O group is the H bond acceptor in the hydrazides. 2. Decomposition of the three-component associates of 1-fluoroacyl-1,2-dimethylhydrazides and protonation of the nitrogen atom in a medium of MeCN take place in the reaction of these molecules with perchloric, picric, and hydrochloric acids. 3. The ratio of the free forms and the forms of the hydrazides protonated with respect to the N2 atom is dependent on the inductive properties of the R substituent in the acyl fragment. The smallest contribution of the protonated form is observed with R=CF3, and the strength of the NH...N2 bond is highest.
