(Chemical Equation Presented) An efficient procedure for the gram-scale preparation of 2-(trimethylsilyl)phenyl trifluoromethanesulfonate, a versatile precursor to o-benzyne, is presented. The three-step sequence utilizes phenol as the starting material, requires only one chromatographic purification, and ultimately delivers the desired silyltriflate in 66% overall yield. 2009 American Chemical Society.
Synthesis of substituted phenols by directed ortho-lithiation of in situ N-silyl-protected O-aryl N-monoalkylcarbamates

A simple, high-yield procedure has been developed for the ortho-lithiation and subsequent ortho-substitution of phenols by a manifold of electrophiles. N,C-Dilithiation of O-aryl N-monoalkylcarbamates proved to be impossible due to a cleavage reaction of
