have been used to generate iminiumions from aminals and aminol ethers derived from secondary alkylamines, including glycine derivatives, in aprotic media which were shown to undergo reactions with electron rich aromatic heterocycles, including furan, to give mono-aminoalkylation products in good yields. Whereas chlorotrimethylsilane has been shown to generate iminiumions from aminol ethers, no evidence
