Effects of formation of an adduct of trialkylpyrazole with CdBr₂ in ¹⁵N NMR

Abstract

The¹⁵N NMR chemical shifts for the analogous diamagnetic adduct of 3,5-dipropyl-4-ethylpyrazole with cadmium dibromide were measured to obtain reference data for estimating the isotropic paramagnetic NMR shifts of nitrogen in paramagnetic adducts of alkylpyrazoles with transition metal salts. The¹³C and¹H NMR spectra were obtained for the same adduct in conditions of frozen protometallotropic rearrangement of the hydrogen in the NH group and the temperature-dependent NMR spectra of isotopes of Cd were made.
