As a part of a research program for pharmacologically interacting sym-triazine derivatives with hexahydrotriazine ring, novel hexahydrotriazine derivatives (1?13) were successfully synthesized. The synthesis of hexahydrotriazines was carried out from the assembly of three molecules of various amines and three molecules of formaldehyde by “1 + 1 + 1 + 1 + 1 + 1” cycloaddition. The synthesis mechanism is probably passes through imines, which trimerizes to give the hexahydrotriazine ring. All synthesized hexahydrotriazines (1–13) were screened for their cytotoxic activity by cancer cells. As a result, compound 1–9 reduced the viability of T98G cells in a concentration-dependent manner. At a concentration of 100 μM, compound 9 exhibited the greatest cytotoxicity at 94.6%. The reason is that compound 9 is C5H5N that has a resonance hybrid structure and exhibits aromaticity. It is considered to be active because it has a structure that is a raw material for pyridine derivatives as mainly medicines and pesticides.

We develop a visible light-promoted divergent cycloaddition of α-diazo esters with hexahydro-1,3,5-triazines, leading to a series of aziridine and imidazolidine frameworks in average good yield, by simply changing the reaction media used. It is noteworthy that the reaction occurs under sole visible light irradiation without the need for exogenous photoredox catalysts. More significantly, a reasonable reaction mechanism was proposed on the basis of the control experiments and density functional theory calculation results.

The three substituted triazines were synthesized by ultrasound irradiation method and characterized by FTIR, 13C NMR, and 1H NMR. The corrosion inhibition behavior of the synthesized inhibitors on N80 steel in 15% HCl was studied using electrochemical analyses and weight loss methods. All three inhibitors exhibited excellent corrosion inhibition performance, and the best inhibition effect was shown by TZ-3 (93.2% at 800 mg/L). EIS measurements suggest that the corrosion inhibition process is a charge transfer controlled. The PDP results indicated that all the triazines are mixed-type inhibitors. Langmuir adsorption model is the best fit among the other tested isotherms. These molecules can act as promising acidizing corrosion inhibitors for the oil gas industry. FTIR, AFM, and UV-vis studies corroborate the adsorption of inhibitor molecules over the metal surface.
