Microwave Assisted Synthesis of Triaryl Cyanurates
摘要:
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.
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

A nickel-catalyzed cyanation of phenolderivatives activated by 2,4,6-trichloro-1,3,5-triazine (TCT) using aminoacetonitrile as the cyanating agent is described. This catalytic system delivered the desired products in moderate to good yields with good substrate compatibility. The readily available starting materials, cost-effective nickel catalyst and metal-free cyanating agent are the major features

In this study, the direct Nickel-catalyzed Suzuki–Miyaura coupling reaction of phenols and arylboronicacids via C–O bond activation using 2,4,6-trichloro-1,3,5-triazine (TCT) is described. Initially, phenols were reacted with TCT to give the corresponding 2,4,6-triaryloxy-1,3,5-triazine (TAT) products. Subsequently, arylboronicacid, base and Ni-catalyst were added to the generated aryl C–O electrophile

A newmethod for C–O bond activation of phenolic compounds has been achieved using 2,4,6-trichloro-1,3,5-triazine to utilize in one-pot Ni-catalyzed deoxygenation and reductive homocoupling reactions. With this simple method, phenolic compounds were converted to their corresponding arenes or biaryl compounds under mild conditions. The introduced methodology has a broad scope and demonstrates good functional
