Method for producing ethylenically unsaturated graftable orthoesters

Method for producing ethylenically unsaturated graftable orthoesters

Ethylenically unsaturated graftable monomers are prepared by reacting hydroxy substituted orthoesters with electrophilic reagents, an alkaline reagent, and a phase transfer catalyst. Preferably the hydroxy orthoester is 4-hydroxymethyl-2-methoxy-2-methyl-1,3-dioxolane, and the preferred reagent is a...

Zusammenfassung:Ethylenically unsaturated graftable monomers are prepared by reacting hydroxy substituted orthoesters with electrophilic reagents, an alkaline reagent, and a phase transfer catalyst. Preferably the hydroxy orthoester is 4-hydroxymethyl-2-methoxy-2-methyl-1,3-dioxolane, and the preferred reagent is acryloyl chloride with sodium hydroxide as the base and methyltrialkylammonium (C8-10) chloride as the phase transfer catalyst.
