Abstract
The reaction of sulfur with primary or secondary amines and formaldehyde has been studied. A simple one step process for the preparation of thioformamides (RR′NCHS; R  H, R′  CH3, C2H5; R  R′  CH3, C2H5; R+R′  (CH2), (CH2), C2H4OC2H) and the amine salts of N, N‐dialkyl‐dithiocarbamic acids (R2NCS2 · H2NR2, R  CH3, C2H5, C4H9; R2  (CH2), (CH2), C2H4OC2H) is reported. In addition, the isolation of diethylamidosulfoxylic acid, (C2H5)2NSOH · 1/2 H2O, the first derivative of a new class of compounds, is described. The physical properties and the 1H‐NMR. spectra of the above mentioned compounds are given.
