AbstractA convenient route is reported for the synthesis of substituted 1,3,4‐thiadiazolo[3,2‐a]‐1,3,5‐triazine‐5,7‐diones and isoxazolo[2,3‐a]‐1,3,5‐triazines. Condensation of the appropriately substituted 2‐amino‐1,3,4‐thiadiazole and 3‐aminoisoxazole with phenoxycarbonyl isocyanate provides the desired target compounds in fair yield.

Abstract High molecular weight soluble polyphenyl-as-triazines were prepared at ambient temperature in m-cresol by the cyclopolycondensation of 2,6-pyridinediyl dihydrazidine (diamidrazone) with various aromatic dibenzil type reactants. Clear lemon yellow films, which exhibited good toughness and flexibility, were cast from solution.

The vibrational spectra of s-triazine and s-triazine-d3
Spectrochimica Acta, 1961Abstract The infrared and Raman spectra of s-triazine and s-triazine-d3 have been taken and an assignment of the fundamental vibrational modes has been made. Nearly all the remaining observed bands are accounted for as combinations or overtones. A simple valence force field normal co-ordinate analysis was made, and the values of some force constants ...

Abstract Three technically feasible routes have now been established for preparation of linear perfluoroalkylene triazine polymers. The most advanced route is based on addition polymerization of long chain fluorocarbon dinitriles and diamidines, followed by acylation and cyclodehydration to triazine polymer.
