Thermal destruction of the binuclear monofluoroacetate complex Cu2(CH2FCOO)4 deposited on zeolite Y was studied by the TG-DTA and ESR methods. Large particles of copper oxide are not formed and fine dispersion of CuO in the matrix is observed due to low temperatures of the destruction of the supported complex (240–250°C) and restriction of the process mainly to large cavities of the zeolite.

The reactions of methyl α-(2-formyl-1H-pyrrol-1-yl)carboxylates with N-substituted aliphatic 1,2-, 1,3-, and 1,4-diamines afford new pyrrole-containing heterocyclic systems: 1,2,3,10b-tetrahydroimidazo[1,2-a]pyrrolo[2,1-c]pyrazin-5(6H)-ones, 1,3,4,11b-tetrahydro-2H-pyrrolo[2′,1′:3,4]pyrazino[1,2-a]pyrimidin-6(7H)-ones, and 1,2,3,4,5,12b-hexahydro-pyrrolo[2′,1′:3,4]pyrazino[1,2-a][1,3]diazepin-7(8H)-ones. The reduction of these compounds with different reagents was studied.

Reaction of 3-aryloxy-4-methyl-3,6-dihydro-2H-pyrans with peracids takes place stereo-selectively to give trans-3-aryloxy-4-methyl-4,5-epoxytetrahydropyrans.

The IR absorption spectra of hexathiocyanate complexes of nickel (II) were studied in the crystalline state (400–4000 cm−1) and in aqueous solutions (2000–2400 cm−1). All the investigated compounds contained monodentate isothiocyanate groups.

The energetics of isomerization and fragmentation of carboxylic acids and their esters from the furan series were investigated in conditions of resonance electron capture with the formation of negative ions. The enthalpies of formation of fragmentary negative ions were determined and the structure of some charged and neutral products of dissociation of these compounds was established. Schemes of the hydrogen and backbone rearrangements were proposed.
