An approach to the synthesis of new 1,4-disubstituted 1,2,3-triazoles, in which one or both substituents contain the cobalt bis(1,2-dicarbollide) fragment, was suggested based on the 1,3-dipolar cycloaddition of azides to alkynes catalyzed by copper(

Differences between the IR and Raman spectra of the dicaprolactamates of Mg, Ca, and Ba indicate differences in their structures. Barium dicaprolactamate has an ionic structure, while the dicaprolactamates of Mg and Ca are partially covalent and have

Based on analysis of the IR and Raman spectra of Na and K caprolactamates it has been established that these exist not in two forms (lactamic and lactimic), as previously proposed, but rather in one form, intermediate in structure between these two f

A method for the synthesis of alkoxygallium hydrides (ROGaH2 and (RO)2GaH, where R=Pri, Bui) was proposed. The method is based on the reaction of gallane GaH3 with one or two equivalents of the corresponding alcohol. Thermolysis of these compounds wa
