Abstract
The polyamines which were obtained by the hydrogenation of N-substituted 2-methyl-2-nitropropylamines, were derived to the corresponding guanidine derivatives with S-methylisothiourea sulfate. Some polyamines were not derived to the guanidine compound, but to the sulfates of starting materials. The material 2-methyl-2-nitropropylamines were prepared by the condensation of 2-nitropropane, formaldehyde and amines.
