tie chair + chair equilibrium of 5-aryl-5-methyl-1,3-dioxanes, unlike that of 1-aryl-I-methylcyclohexanes, is remarkably sensitive to the nature of substituents on the aromatic ring. An interaction involving the the arcmatic group and the dioxane oxygen atoms or C-O bonds is proposed.
Copolymers of the cyclic ketene acetals, 2-methylene-5,5-dimethyl-1,3-dioxane, 3, (MJ with 2-methylene-l,3-dioxolane, 4, (M2) or 2-methylene-1,3-dioxane, 5, (M2), were synthesized by cationic copolymerization. An experimental method was designed to study the reactivity of these very reactive and ext
