CALCULATION OF 15N NMR CHEMICALS SHINS OF CHLORO-CONTAINING FUNCTIONAL DERIVATIVES OF AMINES
The chemical shifts of 15N NMR in a series of model chlorine-containing amines in which one, two and three chlorine atoms are in the α, β and γ positions to the nitrogen atom are calculated. It is established that the most pronounced relativistic effect of chlorine is manifested for the α-position in compounds in which the chlorine atoms are directly connected with the nitrogen atom - about 3 ppm. per one atom of chlorine. On the contrary, for the β and γ positions, the relativistic effects of chlorine are negligible and nonadditive, averaging 1.5 ppm.
