“…We checked the reaction of TCT and PEHA under different conditions to obtain a high yield of tris(pentaethylene-pentamine)triazine (TPEPTA). 49–53 This step has a vital role in the preparation of TPEPTA with high N-ligation sites because a decrease in the substitution of PEHA with chlorine atom in TCT and the total yield of TPEPTA have a significant effect on the highimmobilization of palladium nanoparticles. To obtain the optimized reaction conditions for this step, the reaction of TCT and PEHA was investigated under different circumstances and the obtained results are shown in Table 1S (see ESI † ).…”

Immobilized Pd nanoparticles on a new ligand, namely, tris(pentaethylene-pentamine)triazine supported on graphene oxide (Pd np -TPEPTA (L) -GO) was introduced as a novel and robust heterogeneous catalyst for use in C-C bond formation reaction. The Pd np -TPEPTA (L) -GO catalyst was synthesized by complexation of Pd with TPEPTA as a ligand with high N-ligation sites that were supported on graphene oxide through 3chloropropyltrimethoxysilane. The prepared catalyst was characterized using some microscopic and spectroscopic techniques. The TPEPTA (L) -GO substrate is a 2D heterogeneous catalyst with a high specific surface area and a large amount of N-ligation sites. The Pd np -TPEPTA (L) -GO catalyst used in the C-C bond formation reaction between aryl or heteroaryl and phenylboronic acid derivatives was applied towards the synthesis of biaryl units in high isolated yields. Notably, a series of competing experiments were performed to establish the selectivity trends of the presented method. Also, this catalyst system was reusable at least six times without a significant decrease in its catalytic activity.

“…In an initial study to obtain the proper conditions for the cross‐coupling step, we surveyed the reaction of TCT under different conditions to achieve a high yield of 2,4,6‐triaryloxy‐1,3,5‐triazine (5), because this step has a significant role on the progress of the reaction and total yield. Initially, in order to optimize conditions for this step, we selected the reaction of TCT and para‐cresol as the model reaction under various circumstances such as kind of base and solvent, temperature and the effect of the molar ratio of phenol to TCT.…”

A practical method for the direct amination of phenols using 2,4,6-trichloro-1,3,5-triazine (TCT) as an efficient promotor for the activation of phenols in the presence of an efficient and recyclable heterogeneous catalyst prepared by immobilization of nickel particles on triazole modified chitosan is described.This heterogeneous catalyst has demonstrated a promising activity for the conversion of phenolic compounds to their corresponding amine under mild conditions. Moreover, the obtained catalyst can be reused in five consecutive runs with consistent catalytic activity.

“…We first set out to obtain the proper conditions for our designed protocol using the reaction of phenol and morpholine as simple model substrates. In a preliminary optimization study to find appropriate conditions for the cross‐coupling step, we evaluated the reaction of TCT under various conditions to obtain a high yield of 2,4,6‐triaryloxy‐1,3,5‐triazine ( 4 ) 19. This step has an important role in the progress of the reaction, because decreases in the yield of this step have a significant effect on the total yield.…”

2,4,6-Trichloro-1,3,5-triazine (TCT) was used as an efficient and mild reagent for the direct nickel-catalyzed amination of phenols. This reagent can promote amination of phenols via the activation of the phenolic C À O bond. In this simple protocol, the in situ generated aryl C À O electrophile (Ar-O-TCT) reacts with the desired amine to produce the corresponding arylamine in the presence of a nickel catalyst. This strategy is general for a variety of substrates to give the related arylamines in moderate to good yields. This method was also applied for nickel-catalyzed amination of phenols for the synthesis of primary aromatic amines using the reaction of Ar-O-TCT and ammonium carbonate under mild reaction conditions. With this method, phenolic compounds are converted to their corresponding anilines under mild conditions.
