one‐pot synthesis of N‐(hetero)aryl carbamates through the reaction between alcohols and in‐situ produced (hetero)aryl isocyanates in the presence of a nickel catalyst. The phenolic C−O bond was activated via the reaction of phenol with cyanuric chloride (2,4,6‐trichloro‐1,3,5‐triazine (TCT)) as an inexpensive and readily available reagent. This strategy provides practical access to N‐(hetero)aryl carbamates

Abstract A nickel-catalysedreduction of phenol derivatives activated by 2,4,6-trichloro-1,3,5-triazine (TCT) in ecofriendly 2-methyltetrahydrofuran (2-MeTHF) is described. The phenol-TCT derivatives were readily prepared using grinding method in short time without further purification. This catalytic system allowed the facile C–O cleavage of phenol-TCT derivatives under mild reaction conditions with

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

Rapid synthesis of triaryl cyanurates (2,4,6-triaryloxy- 1,3,5-triazine) was carried out by reacting cyanuric chloride with the sodium salt of hydroxyaryl compounds in water using focused microwaves. Environmentally friendly procedure and isolation of pure products in excellent yields are important features of this method.
