The authors now report observation of the direct silylation of benzene and toluene with a series of chlorotrialkylsilanes under Friedel-Crafts conditions in the presence of Huenig bases (hindered tertiary amines) as proton acceptors. When excess benzene or toluene was heated with chlorotrialkylsilane and aluminum trichloride in the presence of diisopropylethylamine at 150{degree}C in a sealed heavy walled glass tube for 24 h, the corresponding aryltrialkylsilanes were obtained in low, but detactable amounts.
