The oxidative coupling of β-carbonyl imines and allyltrimethylsilane with CTAN were investigated in CH3CN and CH2Cl 2. In CH3CN allylation products were obtained predominantly, while in CH2Cl2, dihydropyrrole products were obtained exclusively. Solvent-assisted nucleophilic cleavage of the intermediate β-silyl cation is proposed to play a role in the solvent-dependent chemoselectivity.
