Abstract: | Tripropargylic esters 2 and 10 of cyanuric and thiocyanuric acids were synthesized. Interaction of these compounds with disubstituted amines gives monoaminoderivatives of dipropargyloxy-s-triazine 4 and 11. Diaminosubstituted propargyloxy-s-triazine 6 was prepared from the corresponding diaminochloroderivative 5. First examples of boron-containing s-triazines 7, 8, 12, 13 were prepared by reaction of propargyl esters 4, 6, 10, 11 with decaborane. New rearrangements of the molecular ions of the 2-aminoderivatives of 4,6-dipropargyloxy-1,3,5-triazine in mass spectrometry were found. |
