![عکس صفحه اول مقاله: Microwave-assisted solid acid-catalyzed one-pot synthesis of isobenzofuran-1(3H)-ones Microwave-assisted solid acid-catalyzed one-pot synthesis of isobenzofuran-1(3H)-ones](/preview/png/5281313.png)
A new, solid acid-catalyzed microwave-assisted environmentally benign synthesis of isobenzofuran-1(3H)-ones is described. Montmorillonite K-10 appeared to be an excellent catalyst for the condensation and successive lactonization reactions. Reaction of phthalaldehydic acid (2-carboxybenzaldehyde) with methylaryl and cyclic ketones was initiated by microwave irradiation and occurred in one step. The reactions were complete in 10-30 minutes providing excellent yields (90-98%).
