N-benzotriazoles: Preparation and Use in Synthesis
Methoxybenzenes and -naphthalenes are benzotriazolylmethylated in the para-position or if this is blocked in an ortho-position.The methylene groups in the products are readily substituted by electrophiles via the lithiated derivatives.Displacement ot the benzotriazole group can be effected by organometallic reagents or by electron-rich benzoid compounds to afford a versatile method for the synthesis of substituted aryl ethers.Key Words: Lithiation/ Grignard reaction/ Condensation/ Aryl ethers/ Diarylmethanes
