Nickel-Catalyzed One-Pot Deoxygenation and Reductive Homocoupling of Phenols via C–O Activation Using TCT Reagent

A new method 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 group compatibility

Nickel-Catalyzed Deoxycyanation of Activated Phenols via Cyanurate Intermediates with Zn(CN)₂: A Route to Aryl Nitriles

A novel, and efficient nickel-catalyzed deoxycyanation of phenolic compounds using relatively nontoxic Zn­(CN)₂ as the cyanide source was developed. The reaction of C–O bond activated phenolic compounds by 2,4,6-trichloro-1,3,5-triazine with Zn­(CN)₂ in the presence of a nickel precatalyst afforded the aromatic nitriles in good to excellent yields

Nickel-Catalyzed Reductive Etherification of Aldehydes at Room Temperature: C–O vs C–C Bond Formation

The reaction of secondary and tertiary benzyl alcohols activated by 2,4,6-trichloro-1,3,5-triazine (TCT) with aldehydes in the presence of NiCl₂·dmg as a precatalyst in ethylene glycol afforded ethers at room temperature. A selective C–O vs C–C bond formation was observed for the secondary and tertiary benzyl alcohols in comparison with primary ones
