Abstract
Esters are prepared by reaction of acyl halides and alcohols or hydroxyalkyl esters and acid halides in the presence of a tertiary amine and polar aprotonic solvents. Bis(2-methacrylatoethyl) phthalate is prepared by the reaction of phthaloyl chloride with 2-hydroxyethyl methacrylate in pyridine and acetone. Bis-phenol-A-bis(2-methacrylatoethyl)ether is prepared from 2,2-bis[4-(2-hydroxyethoxy)phenyl]-propane and methacryl chloride in acetone.
