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.
