Linear a-amidoalkylphenyl sulfones are converted into the corresponding N-acyliminium ions by treatment with TiCl4 at low temperature and then made to react with different nucleophiles such as allyltrimethylsilane, silyl ketene acetal, anisole and thiophene.

Abstract
Linear a-amidoalkylphenyl sulfones are converted into the corresponding N-acyliminium ions by treatment with TiCl4 at low temperature and then made to react with different nucleophiles such as allyltrimethylsilane, silyl ketene acetal, anisole and thiophene.File in questo prodotto:
