Abstract
The present study describes unreported an efficient, sustainable, and green microwave-assisted synthesis of xanthene derivatives using an inexpensive environmentally benign and readily available catalyst boric acid. The synthesis was performed under conventional as well as under microwave-assisted method. The microwave-assisted method has been found to be much more efficient in terms of time and yield of the product. Newly synthesized compounds had been identified on the basis of elemental analysis and spectral data. The method offers several advantages such as short reaction times and milder conditions, easy work-up, and excellent yield of the products.
