A green procedure for synthesis of xanthene derivatives: Micellar solution of sodium dodecylphosphonate catalyzes condensation reaction of aldehydes and beta-naphthol in aqueous media

A green and convenient méthode for the synthesis of a variety of xanthene derivatives by condensation reaction between aldehydes and B-naphthol or dimedone in an micellar solution of sodium dodecylphosphonate is described. This method offers several advantages, such as using of a cheap and environmentally benign reaction media, low loadings of sodium dodecylphosphonate as catalyst and easy work-up
