Green synthesis and self-association of 2,4-diamino-1,3,5-triazine derivatives

RuII and IrIII Complexes Containing ADA and DAD Triple Hydrogen Bonding Motifs: Potential Tectons for the Assembly of Functional Materials

“…The benzyl and hexyl substituted 1,2,3‐triazoles were then synthesized from the deprotected acetylene and the appropriately substituted azide, which was formed in situ from the substituted bromide and sodium azide, through a CuAAC type “click” reaction . Finally the cyano‐ group underwent cyclisation with dicyandiamide in DMSO at 190 °C under sealed tube microwave conditions to give the 2,4‐diamino‐1,3,5‐triazine moiety, as has been observed for other cyano‐ substituted heterocycles …”

Suzuki–Miyaura Coupling of Aryl Sulfonates with Arylboronic Acids Using a Morpholine–Pd(OAc)2 Catalyst System

“…X‐ray data for the precursor triazine γ‐alkylamines (Figures 2, 3), analogous sulfoxides (Figures 4, 5) and literature X‐ray crystallographic data for diamino[1,3,5]triazines39 and associated supramolecular structures27b,c, 40 suggest that hydrogen‐bond‐mediated dimerisation of the triazines is an important interaction in the relatively nonpolar vesicle environment 41. Figure 8 A shows how two triazines might associate to form a dimer consistent with the symmetric structures seen in the solid state for precursor triazine γ‐alkylamines 10 and 17 .…”

Synthesis of Two Complementary Molecular Moulds

“…The nitrile group was then converted into a diaminotriazine group by reaction with dicyandiamide and KOH in 2-methoxyethanol under microwave irradiation. [16] In a first attempt, even with the use of an excess amount of dicyandiamide, only the monodiaminotriazine compound was isolated. To complete the reaction, additional amounts of the reagents (dicyandiamide and KOH) had to be added, and the mixture required additional irradiation.…”
