Abstract

The reaction of nitrosoarenes and 1-(trimethylsilyl)vinilmagnesium bromide in dibutyl ether represents a useful tool for the synthesis of 2-(trimethylsilòyl)indoles by cyclisation of benzene derivatives. The use of more common ethers as solvent leads to large amounts of azo and azoxy derivatives. Conversely, the reaction of nitroarenes and 1-(trimethylsilyl)vinylmagnesium bromide gives conjugate addition products.
