Abstract

As models for the ionization of orthoesters, a series of 1, 3-dioxan-2-ylium salts have been prepared and characterized. The properties of 1, 3-dioxan-2-ylium hexachloroantimonate 1, 5-ethoxymethyl-1, 3-dioxan-2-ylium hexachloroantimonate 2, 2-methyl-5-ethoxymethyl-1, 3- dioxan-2-ylium hexachloroantimonate 3, and 2-phenyl-5-ethoxymethyl-1, 3-dioxan-2-ylium hexachloroantimonate 4, have been studied by 1H and 13C NMR spectroscopy. The ...
