: an Efficient One‐Pot Benzylation of Alcohols
The one‐pot synthesis of symmetrical and unsymmetrical ethers from aldehydes and ketones can be conveniently performed using Yb(OTf)3 as catalyst and triethylsilane as reducing agent in presence of alcohols. This methodology leads to the synthesis of ether derivatives with good yields. Notably, this process resulted a useful tool to protect alcohols as benzyl ether derivatives using differently substituted

Cross-coupling of mesylated phenol derivatives with various potassium alkoxymethyltrifluoroborates has been achieved. The corresponding aryl and heteroaryl alkoxymethyl compounds have been obtained with equal facility with both electron-rich and electron-poor substituents on the activated alcohol.
