The conformational analysis of saturated heterocycles. Part XLV. N-Alkyldihydro-1,3,5-dithiazines and N-alkyltetrahydro-1,3,5-thiadiazines

Abstract
The synthesis, low-temperature n.m.r. spectra, and coalescence ΔG* for ring inversion, and dipole moments of the title compounds are discussed, together with the predominant conformations of these compounds.
