The syntheses of pyrazole amine substituted cyclotriphosphazenes: Spectroscopic and crystallographic characterizations

4‐triphenylmethylaniline substituted cyclotriphosphazene derivatives assisted by multiple phenyl rings

“…In conclusion, the new types of inorganic-organic structures (3)(4)(5)(6) were synthesized by performing the reactions of 4-triphenylmethylaniline and hexachlorocyclotriphosphazene. The structures of cyclotriphosphazene-based compounds were elucidated by standard spectroscopic techniques such as 1 H, 31 P, 13 C NMR, MALDI-TOFF mass analyses.…”

“…The reaction of hexachlorocyclotriphosphazene (1) with 4-triphenylmethylaniline (2) in THF solution by using three different mole ratios (1:2.2, 1:4.2 and 1:6.6) were performed to determine the amount and variety of products. Four different 4-triphenylmethylaniline substituted cyclotriphosphazene derivatives (3)(4)(5)(6) formed (Scheme 1) and the isolated products (3)(4)(5) were characterized by such spectroscopic techniques as MALDI-TOF mass spectrometry, 1 H, and 31 P NMR spectroscopies and elemental analyses. The spectroscopic data and elemental analysis results of synthesized derivatives were provided in the experimental section.…”

“…In the case of primary amines, they attack to phosphorus atom on the cyclotriphospazene ring in both geminal and non-geminal positions, depending on the steric and electronic effects of the amine as well as the nature of the amine groups. [6][7][8][9] For these systems, there are two competing mechanistic pathways to which the amine group attacks: (a) the bimolecular pathway resulting in the non-geminal product, (b) a dissociative process providing the geminal product.…”

“…For this purpose, 4-triphenylmethylaniline (2) was reacted with hexachlorocyclotriphosphazene (1) in three different mole ratios (1:2.2, 1:4.2, and 1:6.6) in tetrahydrofuran (THF) solution at room temperature under argon atmosphere. Resulting from the reactions, three new 4-triphenylmethylaniline substituted cyclotriphosphazene derivatives (3)(4)(5)(6) were synthesized and the isolated compounds were fully characterized by elemental analysis, mass spectrometry, 1 H, and 31 P NMR spectroscopies.…”
