Notes:
Attempts of anionic ring-opening polymerization of benzo-1,3-dioxolan-2-one (1) with sec-butyllithium or potassium dihydronaphthylide as initiators in different solvents and under a variety of reaction conditions revealed that this monomer cannot be polymerized. Possible reasons for this finding are discussed. Benzo-1,3-dioxan-2-one (2) was prepared and characterized for the first time. Anionic ring-opening polymerization of this monomer yields a polymer with a non-uniform constitution, viz., loss of carbon dioxide occurs during polymerization. The mechanism of formation of this polymer is discussed on the basis of product analysis and analysis of the active species formed during polymerization. Attempts to synthesize 5,6-benzo-1,3-dioxepan-2-one (3) failed.
